Abstract

TiPd was investigated as a candidate of high-temperature shape memory alloys. To improve shape recovery, solid-solution hardening by addition of alloying element has been performed. The effect of alloying on martensite transformation temperature, shape memory effect, and yield strength of martensite and austenite phases were investigated. Zr and Hf were found to be effective element to improve shape memory effect. The most important factor to improve shape memory effect of TiPd is temperature to form Ti2Pd3 precipitates rather than strengthening.
