摘　　要：借助于SMA-1型形状记忆合金综合性能测试仪的(ε-R-T)曲线,绘制成50.8at％Ni-Ti合金应力—温度相图,进而讨论了该相图的特性及其应用。A strain - resistance - temperature curve has been measured by means of synthetical characteristic instrument SMT - 1 for the Ti - 50.8at. % Ni shape memory alloy, giving its stress - temperature phase diagram. And the characteristics and applications of the phase diagram are discussed.
