摘要A self-assembled Cu-Fe-Ni-Cr-Si immiscible composite with a bilayer structure was produced by laser induction hybrid cladding (LIHC) as a result of liquid phase separation (LPS). The microstructure exhibited by large amounts of ferromagnetic (FM) Fe3Si particles dispersed within the epsilon-Cu matrix in the upper layer, and many epsilon-Cu particles embedded within the FM Fe3Si matrix in the lower layer. The microhardness values of the Fe3Si matrix lower layer (758HV(0.2)) and epsilon-Cu matrix upper layer (248HV(0.2)) were similar to 7.3 and similar to 2.4 times higher than that of pure copper by LIHC, respectively, indicating that the immiscible composite exhibited strongly inhomogeneous characteristics consistent with a "bilayer structure". Moreover, the immiscible composite showed a high saturation magnetization of 96.2 emu/g and a low coercivity of 7.24 Oe due to the formation of FM Fe3Si with micro-and nanoscaled structures.
