Martensitic Transformation and Effects of Alloying Elements in Ti–Pd Series High-Entropy Shape Memory Alloys
Abstract The effect of alloying elements on the martensitic transformation behavior of Ti–Pd series high-entropy shape memory alloys was investigated. Five compositions incorporating Zr, V, Ni, and Pt were synthesized. DSC analysis revealed that the coherency of the martensitic structure formed by the added elements is crucial for maintaining a high transformation temperature. The findings provide insights into the compositional design of high-temperature shape memory alloys with enhanced thermal stability and functional performance.
