Abstract: Abstract We investigated the effects of hydrogen and temperature on hydrogen embrittlement (HE) of cold-rolled equimolar CoCrFeMnNi high-entropy alloy (HEA). The HE exhibited intergranular fracture in this HEA at 298 and 177 K. At 177 K, more… read more here.

Abstract: Abstract Equimolar CoCrFeMnNi high-entropy alloy (HEA) could be effectively strengthened by grain refinement process. However, the dislocations, grain boundaries and twins determined by the grain refinement process worked as hydrogen diffusion paths and trapping sites… read more here.
