Chanho Lee is a third-year graduate student in the Department of Materials Science and Engineering at the University of Tennessee, Knoxville (UTK) under the direction of Dr. Peter Liaw. Mr. Lee received his M.S. from Sejong University, Korea, in Materials Science and Engineering (MSE) in 2013. During that time, he published four first-author or co-authored papers and received one patent. Since joining the UTK MSE Department in 2014, Mr. Lee has been working on the investigation of the microstructural evolution and mechanical properties of refractory high-entropy alloys (HEAs), especially the influence of additional elements (e.g., Bi, Mg and Sn) on Ti-Fe ultrafine eutectic alloys. He is an expert in the fabrication of metal alloys such as HEAs and bulk metallic glasses using arc-melting suction casting equipment. He is performing in-situ neutron diffraction using the VULCAN Engineering Materials diffractometer at Oak Ridge National Laboratory’s (ORNL) Spallation Neutron Source (SNS) for an in-depth understanding of the mechanical behaviors demonstrated by his modified refractory HEAs. Mr. Lee is also obtaining complementary nano-scale microstructure characterization using atom probe tomography (APT) at ORNL’s Center for Nanophase Materials Science (CNMS). These investigations will be included in the future publication “Lattice Distortion in a Strong and Ductile Refractory High-entropy Alloy” and three additional papers. Mr. Lee presented his results at the 2016 CNMS user meeting and was recognized with a poster award. In 2018, he received the Chancellor’s Citation Award for Extraordinary Professional Promise. His goal, combining in-depth studies of the fundamental materials science and engineering with developing new HEA’s, is to discover advanced materials with superior mechanical properties.
