Deformation twinning is rare in alloys with high stacking fault energy. However, we observed deformation twinning in a micrometer grain-sized compositionally complex steel with a very high stacking fault energy.
Deformation twinning is rarely found in bulk face-centered cubic (FCC) alloys with very high stacking fault energy (SFE) under standard loading conditions. Here, based on results from bulk quasi-static tensile experiments, we report deformation twinning in a micrometer grain-sized compositionally complex steel (CCS) with a very high SFE of similar to 79 mJ/m(2) , far above the SFE regime for twinning (
