▎ 摘  要

NOVELTY - Composite material powder comprises metal base powder and reinforcing body, where the metal powder can be deformed into a sheet-type powder by ball milling process, and the reinforcing body is a nano-one-dimensional and a two-dimensional reinforcing body. USE - Composite material powder of in-crystal distribution reinforcement and preparation and forming method used in aerospace, weapon arming, traffic transportation and other important fields, e.g. aircraft main structure and brake cylinder body. ADVANTAGE - The powder is simple and easy to operate, and has high strength, modulus, carbon nano tube with excellent mechanical property, graphene, silicon carbide and other nano one-dimensional, two-dimensional particles. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a preparation method of composite material powder with reinforcements distributed in crystal; and (2) forming the composite material powder.
