Abstract
The invention provides a green metal composite material, which is prepared by the following method: Provide Mg, Mo, Al, Ni, and Ti powders; weigh the Mg, Mo, Al, Ni, and Ti powders; and perform the first ball milling on the Mg, Mo, Al, Ni, and Ti powders; perform vacuum melting to obtain a Mg-based alloy ingots; crush the Mg-based alloy ingots; provide carbon nano tubes and graphene powders; and perform surface modification; mix well the crushed Mg-based alloy ingots and the surface modified carbon nano tubes and the graphene powders, and perform a second ball milling to obtain a second mixed powder; then perform a first heat treatment to obtain a third mixed powder, then perform a second hot pressed sintering. The process technology of this invention solves the problems of poor compatibility, easy to be segregated and unstable property of the non-metallic particles and metallic matrix.
