▎ 摘　　要

NOVELTY - The graphene reinforced austenitic steel composite material, comprises graphene, 94.65-0.6 wt.% martensite and 5.35-99.4 wt.% austenite. The austenite is formed by the high-energy beam irradiating a mixture of graphene powder and martensite steel powder to induce austenite transformation. USE - Graphene reinforced austenitic steel composite material. ADVANTAGE - The method enables preparation of graphene-reinforced austenitic steel composite material with high tensile strength and improved elongation and impact toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for uniformly dispersing graphene in martensitic steel and inducing austenite transformation.
