摘要： The present invention provides a preparation method of a light metal/boron carbide composite material, comprising: (A) providing a boron carbide precursor and a light metal powder to perform a pretreatment mixing process to form a precursor; (B) performing a vacuum hot pressing molding or a vacuum cold isostatic pressing molding on the precursor to make the precursor form a light metal/boron carbide compound green body that is uniform; (C) performing a thermal treatment on the light metal/boron carbide compound green body to make the light metal/boron carbide compound green body form a light metal/boron carbide compound sintered body; and (D) performing a cold rolling treatment or a hot rolling treatment on the light metal/boron carbide compound sintered body to obtain a light metal/boron carbide composite material.
