Green metal composite material

A green metal composite material, characterized in that:

• the green metal composite material mentioned in this patent is prepared by the following method:
• Provide Mg, Mo, Al, Ni, and Ti powders;
• Weigh the Mg, Mo, Al, Ni, and Ti powders according to a predetermined chemical formula;
• Perform a first ball milling on the Mg, Mo, Al, Ni, and Ti powders after weighing to obtain a first mixed powder,
• Perform vacuum melting on the first mixed powder to obtain a Mg-based alloy ingots;
• Crush the Mg-based alloy ingots;
• Provide carbon nano tubes and graphene powders;
• Perform surface modification on the mentioned carbon nano tubes and graphene powders;
• 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 on the mixture to obtain a second mixed powder;
• Perform a first heat treatment on the second mixed powder to obtain a third mixed powder;
• Perform a second hot pressed sintering on the third mixed powder.
