JPW delivered a seminar for the Department of Mechanical & Energy Engineering at Indiana University/Purdue University at Indianapolis. The discussion and engagement at the conclusion of the seminar were excellent! Thank you to Dr. Shengfeng Yang and Dr. Babak Anasori for the invitation!
Ph.D. student Caleb Clement is lead author on a new paper that demonstrates the ion irradiation performance of Ni-based Alloy 625 is agnostic to fabrication method (PM-HIP versus forging). Post-doc Yangyang Zhao and Ph.D. student Patrick Warren are co-authors. This work is part of our ongoing irradiation campaign on PM-HIP nuclear structural alloys supported by NSUF and EPRI. Congratulations, Caleb!

We have a new award “Degradation Assessment of Advanced Welds for Pressure Vessels” supported by the US Nuclear Regulatory Commission. The project aims to understand irradiation embrittlement mechanisms in reactor pressure vessel (RPV) steel weldments. This is a collaboration with Prof. Maria Okuniewski. We are seeking two US citizen Ph.D. seeking graduate students for this project.
