摘要(Abstract)：

采用单辊旋淬法制备出Fe69Co8Nb7-xVxB15Cu1(x=0,2,5,7)系列非晶合金,将非晶合金在不同温度进行退火,通过X射线衍射仪、透射电镜和B-H磁滞回线仪对退火后合金的微观组织和软磁性能进行分析。结果表明:退火温度对合金的微观组织和软磁性能影响显著,当TaTx2时,由于α-Fe(Co)晶粒粗化和非磁性相的析出,合金的软磁性能急剧恶化。其中Fe69Co8Nb5V2B15Cu1非晶合金在580℃退火1 h,表现出极为优异的软磁性能,其Bs=1.15 T,Hc=0.9928 A/m,μi=48460,而Fe69Co8V7B15Cu1非晶合金在650℃退火1 h,则发生软磁到硬磁性能的转变。
