Plasticity in Additively Manufactured Stainless Steel 316L

Ph.D. Candidate Chris Bean investigated plastic localization in AM microstructure: International Journal of Plasticity Volume 159, December 2022, 103436  Additively manufactured 316L stainless steels display significantly higher yield strength than their as-cast or wrought counterparts. This is associated with the micro-scale cellular structure and complex grain and sub-grain structure, resulting from high cooling rates occurring …

Science/AAAS Article: Deformation fingerprints will help researchers identify, design better metallic materials

Engineers can now capture and predict the strength of metallic materials subjected to cycling loading, or fatigue strength, in a matter of hours – not the months or years it takes using current methods. In a new study, researchers from the University of Illinois Urbana-Champaign report that automated high-resolution electron imaging can capture the nanoscale …

Plenary Speaker at SuperAlloys2022

Dr. J.C. Stinville will give a plenary talk at SuperAlloys2022 on Plastic localization and Fatigue Strength in Polycrystalline Nickel-Based Superalloys. Abstract: Correlations between fatigue strength and monotonic strengths such as yield strength and ultimate tensile strength exist for polycrystalline face-centered cubic (fcc) and hexagonal close-packed (hcp) alloys. It is observed that fatigue strength increases with …

Sharing Data and Know-how in Materials Science

We believe sharing openly the expertise and Data is of primary importance in Materials Science. Advanced datasets or knowledge on advanced experiments are too often restricted to a few research groups. We believe that research can be accelerated by sharing the know-how and state-of-the-art dataset. Consequently, Advanced experimental techniques used in the group or among …
