摘　　要：用发射穆斯堡尔谱学结合其他研究手段分析研究了ＮｉＴｉ形状记忆合金经不同温度、等时（３０ｍｉｎ）退火及经７００℃水淬和５００℃时效后的缺陷、析出相等微观结构的变化情况，并对近等比ＮｉＴｉ合金经７００℃水淬和５００℃时效后能具有好的记忆性能的原因给出了解释。The emission Mossbauer spectroscopy in combination with other methods was used to study NiTi shape memory alloy(SMA) after the sample was water quenched from 700℃ and aged at 500℃ and isochronal annealing at different temperatures. The Ni56Ti44 phase in NiTi SMA has been obtained after different heat treatments. The reason why the NiTi SMA has the best shape memory property after quenching from 700℃ and aging at 500℃ is also given.
