Microstructure Refinement of a Transformation-Induced Plasticity High-Entropy Alloy [PDF]

Materials, 2021
High-entropy alloys (HEAs) have attracted extensive interest due to their unprecedented structure and mechanical performance. We recently proposed a series of novel corich twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) HEAs with superior tensile properties at room temperature; however, the hot deformation behavior has ...
