摘要
it is reported in literature those the effect of microadditional cerium on annealing embrittlement of Fe-B-Si amorphous alloy is negligible even negative.The test result of present paper shows that the annealing embrittlement temperature of Fe76B15Si9 can be increased by 80℃after cerium has been microadded.The cause of the divergence of the test result from those in the literature was analysed.The condition with the positive effect of microadditional cerium on annealing embrittlement temperature of Fe-B-Si amorphous alloy was approached.The reason why microadditional cerium may be ineffective even negative on annealing embrittlement temperature was preliminarily elucidated.
