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.

快速凝固后室溫下合金的組織由柱狀Ｂ２相和粒狀亞穩相構成；亞穩相是由Ｔｉ、Ｎｉ兩元素原子構成的無序面心立方結構；快速凝固后合金中的空位呈短程有序分布，而在４５０℃５ｍｉｎ時效后呈長程有序分布，在電子衍射圖上形成１／２１００和１／４２１０額外斑點。

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.

實驗結果表明，淬火態ＣｕＡｌＮｉＭｎＴｉ合金在馬氏體態時效過程中發生馬氏體穩定化現象；在這一過程中ＤＯ３長程有序度無明顯變化，但發生了原子短程無序。

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

在馬氏體狀態時效，ＤＯ_３長程有序度無顯著變化，沒發生類似在母相態的再有序化，主要是原子短程無序化。
