退火fe_(73.5)cu_1nb_3si_(13.5)b_9合金中α-fe(si)晶化相的有序化
Keywords: fe_(73.5)cu_1nb_3si_(13.5)b_9合金,纳米晶,有序畴,有序度,有序化
Abstract:
？用xrd法研究了退火fe73.5cu1nb3si13.5b9合金中α-fe(si)晶化相的有序化过程.结果表明,fe73.5cu1nb3si13.5b9非晶合金在490℃,1h退火后,α-fe(si)晶化相是具有do3结构的有序相,有序畴为球形,直径为7.0nm,它随退火温度的升高而长大,在590℃退火后达10.9nm,与α-fe(si)的尺寸相当.此时,α-fe(si)的有序度为0.8在850℃,1h退火后,α-fe(si)的do3超点阵线条消失.在550℃等温退火时,α-fe(si)的do3有序畴先为椭球状,于60min退火后形成球状,直径为10nm.
