long-range order

8at% Ni at room temperature is composed of columnar B2 and granular metastable phase;the metastable phase is a disordered Al made up of Ti and Ni atoms;there is a vacancy short-range order in RS TiNi ribbon and a vacancy long-range order in RS TiNi ribbon followed by aging.

快速凝固后室温下合金的组织由柱状Ｂ２相和粒状亚稳相构成；亚稳相是由Ｔｉ、Ｎｉ两元素原子构成的无序面心立方结构；快速凝固后合金中的空位呈短程有序分布，而在４５０℃５ｍｉｎ时效后呈长程有序分布，在电子衍射图上形成１／２１００和１／４２１０额外斑点。

Experimental results show that short range atomic disordering takes place during ageing in the martensite state whereas the long range order degree remians almost unchanged.

实验结果表明，淬火态ＣｕＡｌＮｉＭｎＴｉ合金在马氏体态时效过程中发生马氏体稳定化现象；在这一过程中ＤＯ３长程有序度无明显变化，但发生了原子短程无序。

During parent phase aging, DO_3 atomic reordering occurs, leading to an increase in the degree of long range order.

在马氏体状态时效，ＤＯ_３长程有序度无显著变化，没发生类似在母相态的再有序化，主要是原子短程无序化。
