The possibility of further enhancing the strength of a (CoCrFeNi)₉₄Ti₂Al₄ high-entropy alloy (HEA), which is already strengthened by Ni₃(Ti,Al) second-phase particles, by grain refinement through high-pressure torsion (HPT) is examined. Concomitant with nanograin formation, HPT was found to induce p...
