摘要
基于Slater-Pauling曲线,运用"元素替代"成分设计法则,通过单辊旋淬工艺成功制备出Fe69Co8Nb7-xVxB15Cu1(x=0,2,5,7)非晶合金条带。利用XRD、TEM和DSC对合金系的非晶形成能力、热稳定性进行研究,并通过PPMS和B-H磁滞回线仪研究合金系的软磁性能。结果表明:随着V含量的增加,合金系的非晶形成能力、热稳定性和矫顽力逐渐降低,而饱和磁感应强度、居里温度逐渐增高;当x=2时非晶合金具有最宽两次晶化温度区间,热处理温区宽达225.9℃;当x=7时非晶合金具有最佳高温软磁性能,其饱和磁感应强度为0.96 T,矫顽力仅为8.95 A/m,而居里温度高达TC=349.42℃。
Applying a composition design method of ＂element substitution＂ and based on the Slater-Pauling curve, multi-component amorphous alloy ribbons with compositions of Fe69Co8Nb7-xVxB15Cu1 （x=0, 2, 5, 7, at%） were prepared by a single roller melt-spinning method. The glass forming ability, thermal stability and soft magnetic property were investigated by XRD, TEM, DSC, PPMS and B-H loop tracer. The results show that increasing V content can reduce glass forming ability, thermal stability and coercivity, but increase saturation magnetic flux density and Curie temperature of amorphous phase. The widest heat treatment temperature range of 225.9 ℃ appears in these amorphous alloys with V content of x=2. The desirable soft magnetic property is obtained when x=7, with saturation magnetic flux density of 0.96 T, coercivity of only 8.95 A/m, and Curie temperature up to 349.42 ℃
