Microstructure and magnetic properties of Cu-18Fe in situ composite

Cu-18wt%Fe in situ composite wires were manufactured by inductive melting, casting, forging and heavily cold drawing. The structure and morphology of Cu-18wt%Fe in situ composite were analyzed by XRD, optical microscope and SEM. Magnetic properties of Cu-18wt%Fe in situ composite wires were examined by vibrating sample magnetometer. With the Fe 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 160 x 79.6 A m(-1) and 0.72 at eta =5.42, individually.
