Acta Materialia Silver Medal Award Recipients
The recipient of the 2020 Acta Materialia Silver Medal is Professor Diana Lados, Milton Prince Higgins II Distinguished Professor of Mechanical Engineering and Materials Science at Worcester Polytechnic Institute (WPI). She is also the founder and director of WPI’s Integrative Materials Design Center (iMdc), an industry-government-university consortium with more than 35 members representing all major transportation and defense industries, national laboratories and other governmental organizations, as well as several partner universities.
Prof. Lados earned her B.S./M.S. in Mechanical Engineering from the Polytechnic University of Bucharest in 1997, her second M.S. in Mechanical Engineering from Southern Illinois University at Carbondale in 1999, and her Doctorate in Materials Science and Engineering from WPI in 2004. She held Post-Doctoral, Research Scientist, and Research Prof. positions at the Metal Processing Institute (MPI) at WPI until 2007, when she joined the Mechanical Engineering faculty as an assistant professor and established the iMdc consortium. She was tenured and promoted to associate professor in 2012, was awarded WPI’s Milton Prince Higgins II Distinguished Professorship in 2014, and became a full professor in 2018. She also holds affiliate faculty appointments in WPI’s departments of Physics and Chemical Engineering.
Prof. Lados has brought significant research contributions in the areas of materials and advanced manufacturing, with a special focus on material design, characterization, evaluation, and optimization for fatigue, fatigue crack growth, thermo-mechanical fatigue, creep, and fracture resistance. Her work has established fundamental relationships between materials’ characteristic microstructures and their behavior and properties, and shed light on underlying failure mechanisms – critical considerations in material design and process optimization. She has also developed computational methods and tools that link materials’ performance to their manufacturing processes and resulting microstructures, and provide accurate life predictions. Her advances have had a major impact on both manufacturing and design communities, and have found broad and diverse uses in critical high-integrity structural and elevated temperature applications in transportation and other industries. Prof. Lados has integrated the knowledge, databases, tools, and strategies that she has developed into a unified methodology for sustainable material-process-component design and manufacturing for performance and reliability, creating interdisciplinary bridges between materials science, mechanical engineering, and physics. This integrated material design approach is the foundation of the iMdc consortium, and for its application to the optimization of high-integrity aluminum alloys, Prof. Lados was granted the prestigious CAREER Award from the National Science Foundation (NSF).
Prof. Lados has been at the forefront of research on additive manufacturing (AM) for more than a decade, having developed a fundamental understanding of AM materials and optimization guidelines for their processing and properties, while building comprehensive databases and supporting ICME tools. These advances are helping to expand the use of AM technology to high-integrity structural applications, and are providing original and much-needed methodologies for rapid material and product qualification, standardization, and repair. Her research on additive manufacturing encompasses several materials, fabricated by both direct energy deposition and powder bed processes, using laser and electron beams as heat sources. Her integrated work on advanced manufacturing also includes other technologies such as cold spray processing, friction stir welding, and metal-matrix nano-composites fabrication, and has been consistently funded by both industry and the federal government, through various DoD and NSF grants. These also include equipment grants such as the Defense University Research Instrumentation Program (DURIP) award from DoD and a Major Research Instrumentation (MRI) award from NSF, which have facilitated advanced characterization studies using combined digital image correlation (DIC), electron backscatter diffraction (EBSD), and tomography, as well as non-destructive evaluation studies for in-situ damage detection and monitoring at ambient and high temperatures. This work has resulted in key experimental and computational developments that support the integrated material-process-component design, optimization, and qualification, including creation of property databases and life prediction methods for high-integrity applications. The work has also led to two manufacturing patent developments.
For her work, Prof. Lados had been distinguished with several national and international awards and honors, which include a Fellow of ASM International and a Fellow of Alpha Sigma Mu; the inaugural Constance Tipper Silver Medal from the World Academy of Structural Integrity; the ASM Silver Medal; the Ralph R. Teetor Educational Award from SAE International; the Brimacombe Medalist Award, the Early Career Faculty Fellow Award, and the Robert Lansing Hardy Award from The Minerals, Metals & Materials Society (TMS). At WPI she was recognized with both Sigma Xi Outstanding Junior and Senior Faculty Researcher Awards, and she was named in 2012 one of the 20 “Women to Watch” in New England for significant technical advancements and leadership. She was also selected by the National Academy of Engineering (NAE) to participate in the prestigious Frontiers of Engineering symposia for both exceptional research and innovative education.
The recipient of the 2019 Acta Materialia Silver Medal is Xavier Sauvage, Research Director at CNRS (National Scientific Research Center – France) and Deputy Director of the “Groupe de Physique des Matériaux” (Institute of Physics of Materials) located at the University of Rouen Normandie in France. Dr. Sauvage will receive his Silver Medal during the 2019 TMS Spring Meeting and Exhibition in San Antonio, Texas.
Xavier Sauvage graduated in mechanical engineering from Ecole Normale Supérieure de Cachan (1993-1996) and received a master degree (1996) and a PhD degree (2001) in Physics of Materials at the University of Rouen Normandie. Here, he began to develop expertise on nanostructured metallic alloys, phase transformations, atom probe tomography and transmission electron microscopy. After a short period as a Post Doctoral Fellow at the Max Planck Institute of Stuttgart, he joined the CNRS (National Scientific Research Center – France) for a research scientist position at the “Groupe de Physique des Matériaux” (Institute of Physics of Materials) located at the University of Rouen Normandie in France.
Dr. Savauge has an international reputation as an expert in the field of high resolution chemical analysis (Atom Probe Tomography and analytical Transmission Electron Microscopy) in metallic alloys and, especially, in severely deformed and nanostructured materials. He has developed a large network of international collaborators and has been leader of numerous international projects. His expertise is not limited to characterization down to the atomic scale, but also covers fundamental mechanisms of phase transformations in metallic alloys, the important role of defects and particularly those resulting from high strains. A significant part of his projects has also been dedicated to the relationships between nano-scaled features and material properties. Moreover, part of his activity was devoted to collaborations with industrial partners (Arcellor-Mital, Posco, Michelin, ACOME, Manoir Industries, Nexans). In 2016, he founded the joint research lab IPERS (“Innovation and Performance of Refractory Steels”) with the R&D Department of Manoir Pîtres. Also in 2016, he was promoted to Deputy Director of the GPM (Groupe de Physique des Matériaux), an institute with up-to-date advanced microscopy facilities (including two corrected TEMs, three dual beam SEM-FIB, four atom probes and other equipment). The GPM is organized in five departments dedicated to scientific instrumentation and material science with a total staff of about 170.
His notable research contributions include:
- Three-dimensional atomic scale imaging of (i) co-deformation in multiphase alloys subjected to large strains leading to an understanding of the fragmentation mechanisms in the case of brittle behaviour, and (ii) strain-induced mixing in immiscible model binary systems such as Cu-Fe or Cu-Cr and understanding of the mechanisms leading to the formation of super saturated solid solutions and in metal matrix composite wires (Cu-V, Cu-Nb) processed by drawing.
- Advancing the understanding of (i) strain-induced carbide decomposition in steels, which limits the ductility of cold drawn pearlitic steels; (ii) deformation-induced phase separation and precipitation in model binary aluminium alloys (AlZn, AlCu) and (iii) the mechanisms leading to non-equilibrium grain boundary segregations in severely deformed steels and Al alloys.
These contributions have been recognized by national and European societies: Dr. Sauvauge has been honoured in 2009 by the Société Française Métallurgie et de Matériaux (SF2M, French Metallurgy and Material Society) receiving the Jean Rist Medal and in 2010 by the Federation of European Materials Societies with the FEMS Young Lecturer Award.

The recipient of the 2017 Acta Materialia Silver Medal is Jing-yang Wang, the distinguished professor and division head in the High-performance Ceramic Division at the Shenyang National Laboratory for Materials Science and Institute of Metal Research, Chinese Academy of Sciences. He is also the assistant director of Shenyang National Laboratory for Materials Science.
Jingyang Wang received the B.A. degree in Physics in 1992 from Peking University, M.A. degree in 1995 and Ph.D. degree in 1998, both in Materials Physics from Institute of Metal Research, Chinese Academy of Sciences. He joined the faculty in Institute of Metal Research where he became the assistant professor in 1998, associate professor in 2002, and full professor in 2006. He was the visiting scientist at International Centre for Theoretical Physics (Italy) in 2001, University of Trento (Italy) in 2001, and International Center for Young Scientists (ICYS) at National Institute of Materials Science (Japan) in 2007.
Professor Wang focused over 15 years of research activities in the area of materials science of advanced engineering ceramics. He has published more than 180 peer-reviewed SCI papers (H-index factor 36), including 30 in Acta Materialia and Scripta Materialia, and has 17 patents in the field of ceramics. In addition, he presented ~50 keynote/invited talks and served 25 advisory board members and symposium organizers in international conferences. He is internationally recognized for his scientific contributions and leadership in high-throughput materials design and modeling, novel methods for processing bulk, low-dimensional and porous ceramic materials, and multi-scale structure-property relationship of high performance structural ceramics. His recent notable research contributions are:
He established the theoretical criteria for predicting damage tolerant/quasi-ductile ceramics based on DFT calculations of chemical bonding heterogeneity and specific mechanical properties. Many new families, including MAX phases, RE2SiO5, RE2Si2O7 and M3AlN, were theoretically predicted and experimentally validated as novel damage tolerant/quasi-ductile ceramics.
He proposed the strategic knowledge on tailoring the mechanical properties of nano-laminated carbides and nitrides by means of modifications on valence electron concentration and structural units in crystal structure, and further provided crucial guidelines on experimental activities. His work pioneered extensive investigations of the new family of nano-laminated carbides with the chemical formula of (MC)nAl3C2 and (MC)nAl4C3 (M=Zr and Hf, n=1, 2, 3, and 4).
He presented the concept of optimal irradiation damage tolerance of transitional metal carbides (MAX phase and ZrC1-x) through proper design of intrinsic point defect sinks, including the nano-twinned crystal structure and self-assembly of carbon vacancies, respectively, inside the crystal structures. The knowledge inspired his challenging work on the low-temperature fabrication of the integrated Ti-Cr-Zr-Al-Si-C coating for accidental tolerant Zircaloy fuel cladding.
He developed the integrated theoretical and experimental strategy to conduct high-throughput selection of low thermal conductivity ceramics, and have found more than 20 novel candidates. He also discovered an interesting pressure-induced softening of low-lying optic and acoustic phonon modes and significantly enhanced anharmonicity of Umklapp phonon scattering in complex silicates. The new mechanism could be adopted for phonon engineering and thermal conductivity modulation in lightweight and sustainable low thermal conductivity ceramics without heavy and/or rare earth elements.
He disclosed the diverse dependences of macroscopic performance, including mechanical and thermal properties, as well as high temperature water vapor and CMAS corrosion resistances on chemical composition and crystal structure of dense and phase-pure X2-RE2SiO5 and β-RE2Si2O7 rare-earth silicates. The information would initiate high-efficient materials design and optimization of RE-silicates for advanced T/EBC applications.
He adopted multi-phonon scattering mechanisms in porous high-temperature ceramics that achieved the balance of extremely low thermal conductivity and excellent thermal stability up to 1500 o C. The novel thermal insulation materials covered from highly porous Y2SiO5 and Y2Si2O7 silicates that are originally thermal insulators in dense ceramics to nano-SiC and nano-Si3N4 particle aggregates which intrinsically have very high thermal conductivity in bulk forms.
His contributions have been recognized on many scientific advisory boards and committees of the American Ceramic Society (ACerS) and the American Society of Metals International (ASM Int.) and serves on the International Advisory Board of UK CAFFE consortium (University of Cambridge, Imperial College London and University of Manchester) on ceramics for nuclear applications. He also served as the volume editor of Ceramic Engineering and Science Proceedings and is the book editor of Developments in Strategic Materials and Computational Design, both published by John Wiley & Sons, Inc., and is the Executive editor of Journal of Materials Science and Technology published by Elsevier.
