    摘要:

    基于Slater-Pauling曲線，運(yùn)用“元素替代”成分設(shè)計(jì)法則，通過單輥旋淬工藝成功制備出Fe69Co8Nb7-xVxB15Cu1 (x=0, 2, 5, 7)非晶合金條帶。利用XRD、TEM和DSC對合金系的非晶形成能力、熱穩(wěn)定性進(jìn)行研究，并通過PPMS和B-H磁滯回線儀研究合金系的軟磁性能。結(jié)果表明：隨著V含量的增加，合金系的非晶形成能力、熱穩(wěn)定性和矯頑力逐漸降低，而飽和磁感應(yīng)強(qiáng)度、居里溫度逐漸增高；當(dāng)x=2時(shí)非晶合金具有最寬兩次晶化溫度區(qū)間，熱處理溫區(qū)寬達(dá)225.9 ℃；當(dāng)x=7時(shí)非晶合金具有最佳高溫軟磁性能，其飽和磁感應(yīng)強(qiáng)度為0.96 T，矯頑力僅為8.95 A/m，而居里溫度高達(dá)TC=349.42 ℃。

    Abstract:

    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 oC 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 oC.
