本文综合论述了非晶态合金的退火脆化具有明显的成分依赖性，并对组织结构和制备工艺比较敏感。微量杂质元素的偏聚显著增大合金的脆化倾向，而微量稀土元素铈的适当添加则可以明显减轻杂质元素的不利影响，使延性得到改善。快速退火滞后了合金结构的变化过程，可有效地抑制磁性优化退火过程中非晶态合金的延—脆转化的发生。
This article comprehensively discusses the amorphous alloy annealed embrittlement has obvious composition dependence, and the structure and preparation process is more sensitive. The segregation of trace impurity elements significantly increases the embrittlement tendency of the alloy, and the proper addition of trace rare earth element cerium can obviously reduce the adverse effects of impurity elements and improve the ductility. Rapid annealing lags behind the change of the alloy structure, which can effectively suppress the occurrence of ductile-brittle transformation of the amorphous alloy during the magnetic annealing.
