Tyler passed his PhD defense! Many Congratulations!

Tyler passed his PhD Defense! Many Congratulations, Dr. Flanagan!

Tyler recently accepted the job offer from the Evans Analytical Group (EAG) in the middle of Silicon Valley at California, where I spent my first five years in US. I wish he continues to make a great success in a new place. Congratulations! Yeah!

Seok-Woo gave two invited talks (KITECH and Korea University)!

Seok-Woo gave two invited talks. The title of talk was “Superelasticity of ThCr2Si2-structured intermetallic compounds: Making and Breaking Bonds“. These talks summarized our research on superplasticity of ThCr2Si2-structure intermetallic compounds for the past five years at UConn.

One invited talk was given at Korea Institute of Industrial Technology on August 11, and the other was given as the Department Seminar in the Department of Materials Science and Engineering at Korea University on August 18,

Seok-Woo receives the DOE-BES funds for the next three years!

Seok-Woo receives the DOE-BES fund ($400,000) for the next three years! Seok-Woo’s group will work on the effects of sample dimension on tensile ductility of single crystalline niobium, tantalum, and tungsten at cryogenic temperatures using in-situ cryogenic nano mechanical testing. This work will also use the advanced computer simulations of dislocations (Discrete Dislocation Dynamics and Molecular Dynamics) to understand how dislocations behave in a confined volume. This project will give us a new insight into fundamental understanding of tensile ductility at the micrometer scale!

Seok-Woo receives the collaborative fund from US Army Research Laboratory!

Seok-Woo (co-PI) receives the collaborative fund with Profs. Mark Aindow (PI) and Avinash M. Dongare (Co-PI) from US Army Research Laboratory. These three groups will work together on Wire-Arc Additive Manufacturing (WAAM) with US ARL and VRC Metal Systems. Our group will investigate the micro-mechanical properties of WAAMed materials (Inconel and Steel). Additive manufacturing is one of the main research topics in Materials Science and Engineering, and it is wonderful for us to make a contribution to AM technologies!
