摘　　要：在非晶态Ｆｅ７６Ｂ１５Ｓｉ９合金中加入Ｃｅ可明显改变合金的退火脆化倾向，Ｃｅ与杂质元素化合生成高熔点的化合物，在晶化过程中成为晶体形成的核心，加快了非均匀成核速率，降低了开始发生晶化的温度，但对其晶化反应进行顺序及晶化产物不产生影响．Effects of micro-addition of Ce on annealing embrittlement and crystallization of Fe76B15Si9 metallic glasss have been studied. Micro-addtions of Ce obviously affect the susceptibility to embrittlement of Fe76B15Si9 metallic glass and form stable particles in strips by reacting with impurities; these particles act as nucleating center and accelerate the inhomogeneous nucleation, and as a result, lower the crystallization onset temperature for amorphous Fe76B15Si9 alloy; but do not affect the sequence and resultants of crystallization.
