▎ 摘　　要

The selective laser melting (SLM) forming of graphene/aluminum (Al) composites is difficult. Herein, the graphene/Al composites are successfully fabricated by SLM, and the printing process parameters are optimized experimentally. The anisotropic and elastoplastic characteristics of the graphene/Al composites by SLM are explored by the nanoindentation experiments first. The mesoscopic crystal plastic finite element (CPFE) model of the graphene/Al composites is developed, considering the microstructure characteristics from experiments, which presents a great agreement with the experimental data. The strengthening mechanism of graphene with various geometric sizes reinforced Al matrix composites is investigated by the novelly coupled experimental and CPFE methods.
