Journal ArticleDOI
Temperature-dependent universal dislocation structures and transition of plasticity enhancing mechanisms of the Fe40Mn40Co10Cr10 high entropy alloy
Jin-Kyung Kim,Ji Hoon Kim,Hyojin Park,Jin-Seob Kim,Guanghui Yang,Rosa Kim,Taejin Song,Dong-Woo Suh,Jongryoul Kim +8 more
TL;DR: In this article, the authors present an in-depth characterization of the defects involved in deformation at room temperature (298 K) and subzero temperature (223 K) of the cold-rolled and annealed Fe40Mn40Co10Cr10 alloy.
Journal ArticleDOI
Heterostructured alloys with enhanced strength-ductility synergy through laser-cladding
Rae-Eon Kim,Eun Seong Kim,G. M. Karthik,Gang Gu,S. Y. Ahn,Hyojin Park,Jongun Moon,Hyoung Seop Kim +7 more
TL;DR: In this paper , the authors proposed a simple process to develop heterostructured alloys by laser-cladding a thin layer of an identical material on the surface of the wrought material.
Journal ArticleDOI
Differential superplasticity in a multi-phase multi-principal element alloy by initial annealing
Journal ArticleDOI
Charpy impact toughness of Cu–Fe–Mn-based immiscible medium-entropy alloys
TL;DR: In this article , the impact toughness at ambient and cryogenic temperatures was investigated with fracture analysis for immiscible medium-entropy alloys, and two types of alloys exhibited different impact toughness behavior at different temperatures, while exhibiting higher impact toughness values than those of dual-phase steels with a similar strength level.
Journal ArticleDOI
Cryogenic tensile behavior of laser additive manufactured CoCrFeMnNi high entropy alloys
Eun Seong Kim,K.R. Ramkumar,G. M. Karthik,Sangguk Jeong,S. Y. Ahn,Praveen Sathiyamoorthi,Hyojin Park,Yoon-Uk Heo,Hyoung Seop Kim +8 more
TL;DR: In this paper , the microstructural evolution, tensile properties, and deformation behavior of additively manufactured equiatomic CoCrFeMnNi high entropy alloy (HEA) were investigated at a cryogenic temperature (77 K).
