| 摘 要： | 利用不同的热处理制度对ＮｉＡｌＭｎ高温形状记忆合金进行有序化处理，并通过室温Ｘ射线衍射分析，得到ＮｉＡｌＭｎ合金的马氏体结构为３Ｒ。有序度的大小可以利用特征线对的面间距Δｄ来表示。结果表明，分级淬比上淬更有利于合金的有序化。

| Abstract: | The NiAlMn high temperature shape memory alloy was ordered by undergoing various heattreatments.Through the room temperature Xray diffraction,the value of ordering degree was represented by the dWTFZ of the typical pairs.The results showed that the step quench was more superior than the up quench. |
