Effects of heat treatment on tensile properties and shape memory effects OF Ni-Ti-Nb alloy

摘要

The effects of heat treatment on tensile properties and shape memory effects of Ni-Ti-Nb alloy have been studied by tensile test at different temperatures and electrical resistance measurement. It has been shown that below 900 deg. C with the increase of solid solution temperature, cooling rate and aging temperature, yield stress decreases whereas elongation increases; yet above 900 deg.C, yield stress shows no substantial change whereas elongation decreases abruptly.
