▎ 摘　　要

NOVELTY - Method for preparing graphene-enhanced AlSi10Mg (aluminum alloy) nanocomposite material, involves (i) uniformly mixing graphene oxide powder and deionized water to obtain suspension (A), where the mass ratio of the graphene oxide powder and the volume of deionized water is (1-20 mg):1 ml, and (ii) uniformly mixing suspension (A) and AlSi10Mg powder in an ammonia atmosphere at a mixing temperature of 500-800 degrees C, and drying in a vacuum environment to obtain the product. USE - The method is useful for preparing graphene-enhanced AlSi10Mg nanocomposite material for printing and forming composite material (claimed). ADVANTAGE - The method uses deionized water to mix to avoid graphene agglomeration, improves the interface between the reinforcing phase and the matrix in combination and wettability, and provides excellent fluidity to the powder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for printing and forming a composite material, printing and forming the composite material using a laser selective melting technology or an electron beam melting technology.
