【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。更多还原

【Abstract】 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 atn=5.42,individually.更多还原
