Özet
Phase transformation characteristics of an aged NiTiHfPd shape memory alloy were investigated through thermal cycling experiments via the differential scanning calorimetry technique. Effects of heating/cooling rate and thermal cycling on the phase transformation temperatures, enthalpies, and thermal hysteresis valueswere revealed. It was found that phase transformation temperatures and thermal hysteresis values alter considerably with thermal cycling. The transformation temperatures were found to be above 80 degrees C for all the heating rates, which makes this alloy a promising candidate for high-temperature applications in the selected aging conditions.
