摘要
通过真空熔炼、锻造和大量拉拔变形制备了Cu-16Fe-2Cr原位复合材料。用X-射线衍射仪(XRD)、光学金相显微镜和扫描电镜(SEM)观察分析了纤维相结构和形貌,用振动样品磁强计(VSM)测试了Cu-16Fe-2Cr原位复合材料的磁性。结果表明,随着Fe-Cr纤维的细化和沿织构〈110〉方向的定向排列,沿丝材轴向Cu-16Fe-2Cr原位复合材料表现出显著的磁各向异性。随着变形量的增大,Cu-16Fe-2Cr原位复合丝材的矫顽力和矩形度逐渐提高,在η=5.42时分别达到163×79.6A·m^(-1)和0.71。
Cu-16Fe-2Cr in-situ composite wires were manufactured by vacuum inductive melting, casting, forging and heavily cold drawing. The structure and morphology of Cu-16Fe-2Cr in-situ composite were analyzed by XRD, optical microscope and SEM. Magnetic properties of Cu-16Fe-2Cr in-situ composite wires were examined by vibrating sample magnetometer. With the Fe-Cr fibers fined down and aligned with a preferred crystallographic orientation 〈110〉, obvious magnetic anisotropy were found paralleling to the long axis of wires. After higher amounts of deformation, the coercivity and the squareness increase gradually, and reach 163×79.6 A·m^-1 and 0.71 atη=5.42, individually.
