| 摘 要： | 本文研究Fe_(80)B_(20-x)Si_x(x=6,8,10,12)非晶态合金的退火脆性规律,给出了合金成分原料纯度,薄带厚度以及薄带表面状态对非晶态合金退火脆性的影响。铁基非晶态合金在低温退火过程中已明显变脆。这种退火脆性是由非晶态合金亚稳特性决定的结构弛豫所致。

| Abstract: | In this paper,the regularity of annealing embrittlement for amorphous alloys Fe80B20-xSix ( x= 6 , 8, 10, 12) is studied.The effects of composition,purity of the raw materials, thickness and the surface condition of the ribbons on annealing embrittlement of the alloys are shown.Annealed at lower tmperature,Fe-based amorphous alloys have already become brittle. This annealing embrittlement is caused by structural relaxation which is controlled by the metastability of amorphous alloys. |
