Abstract Scope |
High-entropy alloys (HEAs) have emerged as promising candidates for high-temperature shape memory applications owing to their exceptional microstructural stability and tunable mechanical properties. Nevertheless, the intricate relationship between high configurational entropy and martensitic transformation kinetics in systems such as Zr-Ti-Cu-Ni-based alloys remains poorly understood. This study systematically examines the influence of entropy-driven phase stabilization on martensitic transformation temperatures, microstructure evolution, and deformation mechanisms within the Zr-Ti-Cu-Ni system. Specifically, we elucidate the impact of alloying additions on martensitic transformability, anisotropic deformation characteristics, and shape memory/superelastic performance. Our findings advance the fundamental understanding of entropy-mediated martensitic transformations and provide useful insights for designing advanced multicomponent alloys with superior TRIP (transformation-induced plasticity) and shape memory capabilities. |
