Abstract
A Fe40Mn40Co10Cr10 twinning induced plasticity high-entropy alloy was processed by high-pressure torsion, and its microstructure and mechanical properties were studied. The results indicate the absence of typical grain refinement, but rather the original grain size was retained with the formation of strain-induced HCP martensitic phase.
