Journal ArticleDOI
Effects of deformation–induced BCC martensitic transformation and twinning on impact toughness and dynamic tensile response in metastable VCrFeCoNi high–entropy alloy
Yong Hee Jo,Dong Geun Kim,Min Cheol Jo,Kyung-Yeon Doh,Seok Su Sohn,Seok Su Sohn,Donghwa Lee,Hyoung Seop Kim,Byeong-Joo Lee,Sunghak Lee +9 more
TL;DR: In this article, quasi-static and dynamic tensile properties of a metastable VCrFeCoNi HEA were investigated at room and cryogenic temperatures, and they were systematically correlated with the Charpy impact toughness.
Journal ArticleDOI
Effects of solid solution and grain-boundary segregation of Mo on hydrogen embrittlement in 32MnB5 hot-stamping steels
Jisung Yoo,Min Chul Jo,Min Cheol Jo,Seongwoo Kim,Sang-Heon Kim,Jin-Keun Oh,Seok Su Sohn,Sunghak Lee +7 more
TL;DR: In this article, the effects of solute Mo on HE have been rarely studied for developing 32MnB5 steel, and most studies on the alloying of Mo for interfacial cohesion have been conducted theoretically by calculating the cohesive energies in the Fe lattice.
Journal ArticleDOI
Understanding of adiabatic shear band evolution during high-strain-rate deformation in high-strength armor steel
Min Cheol Jo,Selim Kim,Dae Woong Kim,Hyung Keun Park,Sung Suk Hong,Hong-Kyu Kim,Hyoung Seop Kim,Seok Su Sohn,Sunghak Lee +8 more
TL;DR: In this article, the microstructural evolution and formation mechanism of adiabatic shear band (ASB) in a high-strength armor steel were investigated using a laboratory-scale split Hopkinson pressure bar, and the results were correlated with the actual ballistic impact behavior.
Journal ArticleDOI
Effects of Ti alloying on resistance to hydrogen embrittlement in (Nb+Mo)-alloyed ultra-high-strength hot-stamping steels
Jisung Yoo,Min Chul Jo,Min Cheol Jo,Seongwoo Kim,Jin-Keun Oh,Jian Bian,Seok Su Sohn,Sunghak Lee +7 more
TL;DR: In this article, the effect of micro-alloying elements such as Nb and Mo on resistance to hydrogen embrittlement was investigated via controlling Ti content and conducting slow-strain-rate tensile (SSRT) tests and thermal desorption analyses.
Journal ArticleDOI
Effects of Al addition on tensile properties of partially recrystallized austenitic TRIP/TWIP steels
TL;DR: In this paper, the effect of Al alloying on microstructures and tensile properties were investigated in relation to the deformation behavior with TWIP and transformation-induced plasticity (TRIP), which was characterized with electron backscatter diffraction (EBSD) grain orientation spread maps.
