Welcome to the Irradiation Micromechanics Research Group. We are broadly interested in the micromechanics of materials, especially of irradiated and nuclear materials. That is, we try to predict large-scale mechanical behaviors of materials based on our understanding of localized elastic-plastic phenomena associated with atomic- through micro-scale material constituents/features/phases. We utilize miniaturized mechanical testing – often in combination with multi-scale characterization techniques and various modeling approaches – to understand materials properties and performance.
Our major research foci can be grouped as follows:
- Transmission electron microscopy in situ mechanical testing
- Oxide dispersion strengthened alloys and irradiation-induced nanoclusters
- Powder metallurgy and hot isostatic pressing (PM/HIP)
- Technique development
Our research group began at Boise State University in 2013 and relocated to Purdue University in 2016, under the stewardship of Dr. Janelle Wharry. Since the group’s inception, we have received research grants, contracts, and agreements with total value $5.2M. We are endlessly grateful for the generous support from the Department of Energy Office of Nuclear Energy, DOE Nuclear Science User Facilities, National Science Foundation, Electric Power Research Institute, Idaho National Laboratory LDRD Program, Los Alamos/Sandia Center for Integrated Nanotechnologies (CINT), NASA Idaho Space Grant Consortium, Micron Foundation, and Pacific Northwest National Laboratory. We also appreciate the in-kind support from Army Research Laboratory, Electric Power Research Institute, and Idaho National Laboratory.
