Abstract

Abstract

En 中文
• A single-crystal compositionally complex alloy was used to decouple the roles of Schmid factor and temperature in ε-martensite formation. • Partial dislocations are consistently activated under all loading conditions, leading to the formation of intrinsic stacking faults. • ε-Martensitic transformation is governed by the competitive glide of distinct Shockley partial dislocations rather than competition between SPDs and full dislocations. • The interplay between Schmid factor and deformation temperature controls ε-martensite nucleation through modulation of partial dislocation glide.
