Metallic glass have been studied extensively in recent years because of their unique physical,chemical,and mechanical properties.SiC is an excellent composite reinforced phase with low density,high hardness,high strength,low thermal expansion coefficient,strong heat transfer ability and stable property at high temperature.Therefore,in order to reduce the density of metallic glass,improve the comprehensive mechanical properties and expand its application areas,the porous SiC preform is added as the second ph...
