The recipient of the 2017 Acta Materialia Gold Medal is Dr. John J. Jonas, Henry Birks Professor Emeritus, Department of Mining and Materials Engineering, McGill University, Montreal, Canada. Dr. Jonas was born in Montreal and graduated from McGill University with a bachelor’s degree in Metallurgical Engineering in 1954. After working for one year at the Steel Company of Wales in Port Talbot, he attended Cambridge University on an Athlone Fellowship and received a Ph.D. degree in Mechanical Sciences in 1960. On returning to Montreal, he began teaching “mechanical metallurgy” at McGill and built up a research laboratory that includes a number of specialized testing machines and is particularly well equipped for experimental investigations in the field of high temperature deformation.
Professor Jonas’ most important scientific contributions are related to determining what happens to sheet steel when it is red hot and flying through a rolling mill at 100 km/hr. The basic phenomena involved include dynamic and post-dynamic recrystallization, dynamic transformation and retransformation, and the dynamic and strain-induced precipitation of carbonitrides. He and his co-workers have made seminal contributions to all three of these areas of research. An important related innovation was establishment of the laboratory method of determining the Tnr (temperature of no-recrystallization) during rolling, a procedure that is now employed in rolling mills worldwide. This work has resulted in major improvements in the understanding and control of the microstructural changes taking place during steel processing and has led to more accurate computer models for the control of industrial rolling mills.
In addition to his research in ferrous metallurgy, Professor Jonas has made numerous contributions to the understanding of the deformation behavior of non-ferrous metals. These have included explanations of variant selection of twins in Mg and Ti, of the causes of plastic instability and flow localization during metal forming, and of texture development during deformation, annealing and phase transformation.
He has received numerous awards for this work, including the Réaumur and Gold Medals of the French Metallurgical Society, the Hatchett Medal of the Metals Society (U.K.), the Airey, Dofasco and Alcan Awards of the Canadian Institute of Mining and Metallurgy, the Gold Medal of the Canadian Metal Physics Association, the NSERC Award of Excellence, the Killam Prize for Engineering, the Michael Tenenbaum Award of the American Institute of Metallurgical Engineers, the Hunt Silver Medal of the US Iron and Steel Society, the Barrett Silver Medal and G. Macdonald Young Award of the American Society for Metals, the Alexander von Humboldt Research Award (Germany), and the Yukawa Silver Medal and two Sawamura Bronze Medals of the Iron and Steel Institute of Japan. Professor Jonas has been elected a Fellow of the American Society for Metals, Royal Society of Canada, Canadian Academy of Engineering, Canadian Institute of Mining and Metallurgy, and Hungarian Academy of Sciences. He is an Honorary Member of the Iron and Steel Institute of Japan and of the Indian Institute of Metals. He was made an Officer of the Order of Canada in 1993, a Chevalier of the Order of Quebec in 2000, and received the Quebec prize for science (Prix du Québec - Marie Victorin) in 1995. He has served as a visiting professor in numerous countries, including Argentina, Australia, Belgium, Brazil, Britain, China, France, Germany, Holland, Hungary, India, Iran, Israel, Japan, Mexico, South Africa, South Korea, Spain, Taiwan, the USA and the USSR.
In 1985, Dr. Jonas was appointed to the CSIRA/NSERC Chair of Steel Processing at McGill, a position which was funded jointly by the Canadian Steel Industry Research Association and the Natural Sciences and Engineering Research Council of Canada. In this capacity, he worked closely with the Canadian steel industry, and collaborated in the solution of a number of important processing problems. He and his colleagues have been granted five sets of international patents associated with steel rolling, three of which have been assigned to the sponsoring companies.
He has trained over 200 students and research fellows in the specializations outlined above and he and his students have published more than 800 papers, 100 of them in Acta and Scripta Materialia. His current h-index (Hirsch number) is 83 and he has more than 25,000 citations to his credit.
Dr. Jonas will receive the Gold Medal at the TMS Annual Meeting in San Diego in March 2017.
The recipient of the 2016 Acta Materialia Gold Medal is Dr. Sungho Jin, Professor Emeritus of University of California, San Diego. Prior to his recent retirement, he was Distinguished Professor of Materials Science in the Departments of Mechanical and Aerospace Engineering at UCSD and held Iwama Endowed Chair. He also served as the Director of the university-wide Materials Science & Engineering Program at UCSD for the past 13 years.
Sungho Jin received B.S. degree in Metallurgy in 1969 from Seoul National University, and M.S. and Ph.D. degrees in Materials Science in 1971 and 1974, respectively, from the University of California, Berkeley. He joined Bell Laboratories at Murray Hill, New Jersey in 1976 as Member of Technical Staff and later became Technical Manager to carry out forefront materials/devices research for 26 years. He then joined UC San Diego in 2002 for academic educational service and research activities for 13 years. He also served as a Principal Investigator at the Center for Magnetic Recording Research (CMRR) at UC San Diego.
Dr. Sungho Jin contributed to the advancement of science and technology with worldclass, trend-setting research in the broad fields of electronic, magnetic, optical, superconducting, electronic packaging, and MEMS materials and devices, nano-bio materials, and energy materials. The pioneering and leadership nature of his work is evident by his publications (~400 including 10 in Nature or Science), Science Citation Index (~17,000), US Patents (~250 issued or pending), and invited or keynote talks (~140) at major professional societies. His noteworthy accomplishments include: the discovery (and naming) of Colossal Magneto-Resistance (CMR) phenomenon in the perovskite La-Ca-Mn-O in 1994; his publication in Science, “Thousandfold Change in Resistivity in Magnetoresistive La-Ca-Mn-O Films”, which has ~4,000 citations, and touched upon imagination of many scientists and immensely stimulated world-wide research on CMR manganite materials for a variety of electronic and magnetic applications including ultra-high-density magnetic recording and future spintronics devices; his development of ductile permanent magnet alloys of Fe-Cr-Co (Chromindur) based on spinodal decomposition for reliable and miniaturized telephone receiver applications, for which as many as 10 million cup-shaped magnets per year were manufactured and used in-high quality AT&T telephones; he demonstrated, for the first time, the feasibility of high Tc superconductor (HTSC) wires from the mechanically brittle ceramic superconductors; he initiated the trend and displayed leadership in promoting Lead-Free Solders R&D by organizing the first seven “LeadFree Solder” symposia for the Metallurgical Society meetings (1993-1997); and he demonstrated that sharply bent zig-zag carbon nanotubes can be fabricated using changes of electric field direction during CVD growth.
More recently, Professor Jin discovered that vertically aligned TiO2 nanotubes on Ti implant metal surface enhanced bone growth by 300%. He discovered novel electronic switching behavior and logic in CVD synthesized carbon nanotube Y-junctions. He developed “Nano-Solders” that can be soldered at low temperatures but can be converted to a higher-melting-point (415oC), tough and ductile intermetallic compound to enable thermally more durable, fatigue- and creep-resistant solder electronic packaging. He designed and produced drug-delivery, hollow sphere nanocapsules with trapped magnetic nanoparticles for magnetically guided tissue penetration and remotely switchable, on-demand release of anti-cancer medications. He designed and demonstrated Smell-o-Vision scent generating device demonstrated for future TV and cell phone displays to release synchronized scents when the corresponding scenes come up on TV screen. This work received much news media attention in 2011 including ABC, NBC and CNBC TV network coverage and Scientific American coverage. Virtual Reality (VR) headsets capable of synchronized scent release have also been demonstrated. He designed new, highly efficient sunlight absorber layer materials for Concentrating Solar Power (CSP) generator systems. He designed smart textiles that can automatically change insulation in response to ambient temperature change to make a person feel always comfortable, thus saving building electrical energy for air-conditioning or heating.

Robert O. Ritchie
The winner of the 2014 Acta Materialia Gold Medal is Robert O. Ritchie, the H.T. & Jessie Chua Distinguished Professor of Engineering in the Departments of Materials Science & Engineering. at the University of California Berkeley and Senior Faculty Scientist in the Materials Sciences Division at the asscoiated Lawrence Berkeley National Laboratory.

The winner of the 2013 Acta Materialia Gold Medal is André Pineau, currently Emeritus Professor at the Ecole des Mines de Paris’s Centre des Matériaux. André Pineau received an Engineering/Metallurgy degree from the Ecole des Mines de Nancy in 1965, and a PhD degree in Physical Sciences from the University of Nancy in 1969. He joined the Ecole des Mines de Paris in 1965, where he largely contributed to the creation of the Ecole des Mines’s Centre des Matériaux. This Centre has become one of the largest of its kind in Europe specialized in the field of physics and mechanics of materials with about 200 people, including 90 PhD students. He was promoted to Professor in 1978 and was Head of the Ecole des Mines’s Materials Science and Engineering Undergraduate Department from 1979 to 2006. He was responsible for the Centre des Matériaux’s Mechanical Metallurgy Research Unit, associated with the National Scientific Research Centre of France (CNRS), from 1978 to 1994. From very early on in his career, he developed strong links internationally, e.g. with MIT, where he was twice a Visiting Professor at the Materials Science and Engineering Department (for a year in 72/73 and again for 6 months in 1983) working with Professors R. Pelloux, A. Argon and F. McClintock; with Kyoto University in 1977 where he collaborated with Professor I. Tamura on phase transformations in steels.
Professor Pineau’s scientific career has been repeatedly recognized with prestigious awards and honors, including the Rist Price from the Société Française de Métallurgie (SFM) in 1974, the Osmond Price from the Société d’Encouragement pour l’Industrie Nationale (SEIN) in 1983, the H. Becquerel Price from the French Academy of Sciences in 1987, the CNRS Silver Medal in 1989, the Portevin Medal from the Société Française de Métallurgie et Matériaux (SF2M) in 1991, the Gaz de France Price from the French Academy of Sciences in 1992, the Great Medal from SEIN in 1994, the Griffith Medal from European Structural Integrity Society (ESIS) in 1996, the Gold Medal from the Federation of European Materials Societies (FEMS) in 1997, the Honorary Medal from the SF2M in 1999, and the ASTM George R. Irwin Medal in 2011. His contributions have also been recognized with memberships of many scientific advisory boards and committees. Professor A. Pineau was elected as a member of the Comité des Applications of the French Academy of Sciences (CADAS) in 1994, of the French Academy of Engineering in 2000, and as a fellow of the Société Française de Métallurgie et Matériaux (SF2M). He has also been a member of the Editorial Board of the journal on Fatigue and Fracture of Engineering Materials and Structures, and the editor of the Journal of Nuclear Engineering and Design. He was elected as Vice President of the European Structural Integrity Society (ESIS) in 2002, and as an Honorary Member of the Deutscher Verband für Materialforschung und –Prüfung (DVM) Society in Germany. He was a scientific advisor for Electricité de France (EDF) in 1994, for Usinor from 1998 to 2006, and has been for the French Atomic Energy Authority (CEA) since 1980. He has also served as an expert in numerous material and structural failure cases for the nuclear, transportation, pipeline, aeronautical and aerospace industries.
Professor André Pineau has published more than 300 journal articles, including 20 in Acta Materialia and Scripta Materialia, five textbooks, co-authored with D. François and A. Zaoui, and co-edited and co-authored 20 others dealing with the mechanical behavior of metallic materials. He is a passionate educator and has been an inspirational force to many undergraduate students, to the 85 PhD students who studied under his supervision and to his colleagues at the Ecole des Mines and at international institutions. As André Pineau has always been concerned with the education of school children, he is also currently strongly engaged in the development of practical scientific activities in elementary schools.
His early research was devoted to the study of the precipitation strengthening in nickel and iron base alloys. His main contributions in this field, with R. Cozar, were the discovery of the co-precipitation of γ’ and γ” phases leading to the “compact morphology” and to the development of a theory on the raftening of γ’ precipitates in nickel base single crystals, work published in Acta Metallurgica in 1976. He was also involved (with B. Thomas, F. Lecroisey and L. Remy) in a pioneering study which identified the effects of temperature on the stacking fault energy of FCC metals and alloys. His research group also largely contributed to the understanding of the strengthening effect associated with mechanical twinning in low stacking fault energy alloys, such as Fe-Ni-Cr and also Fe-Mn alloys which form now the bases of TWIP steels used in the automotive industry. With R. Pelloux from M.I.T., he also investigated the effect of strain-induced martensitic transformation on the fatigue behavior of unstable stainless steels. In the early 70s, he focused his research activities on high temperature fatigue and creep-fatigue oxidation interactions in nickel base alloys and austenitic stainless steels. His work (with E. Andrieu and R. Molins) showed in particular the existence of a critical oxygen partial pressure below which the fracture mode remains transgranular in Ni base alloys. He identified the mechanisms of oxygen penetration along grain boundaries which are responsible for intergranular fracture of these materials, and the interactions between transgranular fatigue cracks and intergranular creep damage in stainless steels (with C. Levaillant). The resulting understanding and approach has inspired to some extent the R5 assessment procedure for the high temperature response of metallic structures developed in the United Kingdom, in particular those used for the initiation of cracks by creep and fatigue damage. He also conducted a number of studies devoted to multiaxial fatigue, such as the effects of the environment and loading paths on the directional aspect of crack initiation.
In the 80s, André Pineau concentrated his research efforts on the study of fracture (ductile, brittle, ductile-to-brittle transition) in ferritic steels used for the fabrication of nuclear pressurized water reactors (PWR) and in duplex stainless steels. He developed the so-called “local approach to fracture” which is now widely used by engineers and scientists worldwide. This approach, which is mainly based on the micromechanisms of failure ahead of a crack tip, has largely contributed to the improvement of the transferability of laboratory test results to components. His work in this area over the past thirty years has greatly influenced the development of fracture mechanics standards (i.e. fracture toughness characterization and structural integrity assessments), and has thus had a profound impact in failure analysis, structural integrity code and material development in a broad range of industries, such as the automotive, aerospace, nuclear, pressure vessel and piping industries. In 1981, work by one part of his research group (also known as “Beremin”) on cleavage fracture revealed for the first time that the fracture toughness of ferritic steels in the lower shelf regime is not an intrinsic property but depends on specimen size. Since then, the local approach to fracture methodology has become an established discipline in its own right, being largely used to explain a number of results which cannot be easily rationalized using a global fracture mechanics approach. André Pineau is continuing his work on the micro-mechanisms of fracture, in particular the effect of the bimodality of failure modes (cleavage and Intergranular damage) which can be found in thick components containing segregated zones, and the crossing of a grain boundary with a large twist component by a cleavage crack.
Professor Pineau will receive his Gold Medal during the December 2013 MRS Fall meeting in Boston, MA. A symposium, entitled “Materials: Fundamentals of Fatigue and Fracture”, will be held in connection with this award.
