| Summary: | Owing to Nitinol's success, shape memory alloys (SMAs) enjoy unwavering attention as key futuristic intelligent structural materials. Despite the excellent shape memory effect (SME) and pseudo-elasticity, Nitinol is susceptible to high-temperature applications. Extensive research has been conducted to discover SMAs with improved higher-temperature properties by considering PGM-bearing B2 Ti-based compounds. In this study, the impact of palladium (Pd) addition on Ti50Ru50 to yield Ti50Ru50- xPdx ternary compounds with martensitic transformation (MT) was investigated by employing a supercell approach. With the addition of Pd up to 25 at. %, B2 Ti50Ru50-xPdx remained stable (C11>C12), while ternaries with Pd ≥ 31.25 at. % were found unstable (C11<C12). |
