Study on martensitic transformation twinning in ductile metastable body-centered-cubic high entropy alloys
Martensitic transformation twinning including {111}α’’ type I, ‘‘{351}’’< 2‾11 >α’’ type II and {021}α’’ twins, and extrinsic {111}α’’ stacking faults were investigated in a deformed body-centered-cubic (BCC) high entropy alloy (HEA). The interaction between martensitic twinning and local chemical environment variation made great contributions to strain accommodation upon straining, implying a novel route to develop ductile BCC HEAs.

Abstract
Martensitic transformation twinning including {111}α’’ type I, ‘‘{351}’’< 2‾11 >α’’ type II and {021}α’’ twins, and extrinsic {111}α’’ stacking faults were investigated in a deformed body-centered-cubic (BCC) high entropy alloy (HEA). The interaction between martensitic twinning and local chemical environment variation made great contributions to strain accommodation upon straining, implying a novel route to develop ductile BCC HEAs.
