Abstract
It provides a preparation method of solid-liquid composite casting in a specific mold to produce the heterostructured metallic bars composed of high elastic modulus metal and low elastic modulus Mg alloy. Subsequently, the microstructure of heterogeneous Mg alloys bars is adjusted by the specific deformation and heat treatment. Heterogeneous Mg alloys bars without oxide inclusions and with good interfacial bonding were prepared through this method. The improvement of elastic modulus is obtained by tailoring the heterogeneous microstructure.
