▎ 摘　　要

NOVELTY - Graphene reinforced aluminum-magnesium alloy silicon carbide composite material comprises 10-20 pts. wt. magnesium, 1-2 pts. wt. yttrium, 5-10 pts. wt. chromium, 1-2 pts. wt. gadolinium, 6-16 pts. wt. zirconium, 70-80 pts. wt. aluminum, 15-30 pts. wt. nano-silicon carbide, and 5-20 pts. wt. graphene. USE - Graphene reinforced aluminum-magnesium alloy silicon carbide composite material. ADVANTAGE - The composite material can refine grain and improve lattice defects of lattice aluminum-magnesium alloy. It has enhanced grain density, and has improved comprehensive properties including strength, hardness and plasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of aluminum-magnesium alloy silicon carbide composite material by weighing components according to proportion; mixing and ultrasonic dispersing at 750-850 degrees C; cooling; and forming.
