Intergranular Corrosion

Dr. Hyeji Im is an Assistant Professor at
Case Western Reserve University in the
Department of Materials Science and
Engineering whose research centers on
high-temperature materials and their
applica琀椀ons in aerospace engineering.
Her passion for materials science was
sparked during an exchange program in
the United States, where she became
cap琀椀vated by the engineering marvels
behind flight. She pursued a deeper
understanding of the materials that make
such feats possible and con琀椀nues to
explore the development and
op琀椀miza琀椀on of high-performance
materials for turbine engines,
contribu琀椀ng to innova琀椀ons in aerospace
and energy systems.
Dr. Hyeji Im and her team are inves琀椀ga琀椀ng the
poten琀椀al of laser addi琀椀ve manufacturing (AM) to
develop molybdenum alloys as fuel cladding
materials with enhanced corrosion resistance.
This research has two main aims: (1) explore the
poten琀椀al of laser AM as a viable processing
route to develop molybdenum alloy as a fuel
cladding material, and (2) generate quan琀椀ta琀椀on
input data on thermodynamic and diffusional
interac琀椀ons between defects and solutes, which
can serve as a guide for predic琀椀ng intergranular
corrosion.
