Janelle P Wharry

Janelle P Wharry is a Professor in the Department of Mechanical Science and Engineering at the University of Illinois, affiliated with the Materials Research Lab. Her research focuses on irradiation effects, microstructural evolution, and mechanical behavior of advanced materials under extreme conditions. Key areas of interest include austenitic stainless steels, Ni-Cr-Fe alloys, and FeCrAl alloys, with an emphasis on stress corrosion cracking, phase transformations, and radiation tolerance.

Her work bridges fundamental materials science with nuclear engineering challenges, addressing topics such as neutron irradiation-induced phenomena, weld integrity, and materials for nuclear reactors. Notable contributions include studies on dislocation loop-controlled martensitic transformations, in situ TEM analysis of irradiated materials, and mitigation strategies for chloride-induced stress corrosion cracking.

Recent articles highlight advancements in understanding irradiation-induced amorphous-to-crystalline phase transitions, pseudoelasticity in 316L stainless steel, and microstructural analysis of neutron-absorbing materials. Collaborations span nuclear energy innovation, ion irradiation effects on ceramics, and thermal aging of PM-HIP alloys.

Dr. Wharry’s expertise extends to experimental techniques like atom probe tomography and in situ mechanical testing, with a focus on translating microstructural insights into practical solutions for nuclear infrastructure and energy systems.
