用机械合金化方法制备了ＮｉｘＴｉ（１００─ｘ）（ｘ＝１０～７０）合金，用Ｘ射线衍射、ＳＥＭ及ＴＥＭ研究了机械合金化过程中Ｎｉ５０Ｔｉ５０粉末的组织结构变化，最后由ＤＳＣ差热分析研究了Ｎｉ５０Ｔｉ５０非晶态粉末的晶化行为。
NixTi (100─x) (x = 10 ~ 70) alloys were prepared by mechanical alloying. The microstructures of Ni50Ti50 powders during mechanical alloying were investigated by X-ray diffraction, SEM and TEM. The crystallization behavior of Ni50Ti50 amorphous powder was studied.
