非晶态合金切变带可逆切变与退火脆化Reverse Shear of Shear Bands and Annealing Embrittlement in Amorphous Alloy

摘要(Abstract)：
等温退火或连续加热到脆化开始以前,退火前弯曲产生的切变带是可逆的。脆化开始激活能为69—72Kcal/mol,类似结晶激活能67—68Kcal/mol,如后者用X线第一峰等高测定的话。常用DSC(扫描示差热分析)数据制成Kissinger图测出的结晶激活能是错误的,因DSC热分析曲线的结晶开始点或结晶高峰点其X线第一峰高度不等似乎。退火脆化发生以前,切变带内结构改变是稳定的。脆化与结晶初始阶段有关。
