由于相变滞后，ＴｉＮｉ合金可以在同组成同温度下呈现不同的相结构（马氏体和奥氏体〕本文研究了不同相结构对其电化学性能的影响，发现奥氏体和马氏体相结构的吸放氢电化学热力学性能差别不大，但前者的动力学性能更优越．同时还用电阻法测试了ＴｉＮｉ中固溶氢量对相变点Ｍｓ的影响．

The effects of two different phase structures of TiNi on its electrochemical properties were studied. By utilizing the transformation hysteresis, both TiNi samples with austenite and martensite structure were prepared and tested at the same temperature. The former has better kinetic properties than the later. In this paper the effect of hydrogen dissolved in the alloy to form solid solution on phase transformation temperature was also investigated with the electric resistance method.
