非晶态合金退火脆化与热激活

Annealing Embrittlement of Amorphous Alloys and Heat Activation

通过研究非晶态合金退火脆化过程中激活能的变化规律，探讨了脆化激活能与延─脆转变不同发展阶段之间的对应关系，描述了非晶态合金退火脆化过程原子热激活运动的特征．根据脆化激活能随合金成分的变化规律，分析了非晶态合金退火脆化行为的成分依赖性．

In this paper,the correlation between activation energies and different stages in ductile-brittle transition of metallic glasses has been explored,and the features of heat activating motion of atoms concerning the brittling process have been described by studying the changing law of activation energies for embrittlement during the transition.And according to the change of activation energies for embrittlement with varying composition,the compositional dependence of the annealing embrittlement of amorphous alloys has also been analysed.
