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 …
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 …
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 …
