摘要

This study investigates the fabrication of high-quality graphene oxide-reinforced Al5052 composites using the accumulative roll bonding process, focusing on microstructural evolution and mechanical property enhancement. Electron backscattered diffraction analysis revealed significant grain refinement, while Raman spectroscopy confirmed the stability and effective dispersion of GO within the aluminum matrix. Mechanical testing showed remarkable improvements, with yield strength increasing by 172% (from 125 MPa in annealed Al5052 to 340 MPa in the 0.2 wt% GO composite) and ultimate tensile strength (UTS) rising by 80% (from 250 MPa to 450 MPa). Vickers hardness increased by 60% (from 55 HV to 88 HV). These enhancements are attributed to the synergistic effects of grain refinement, dislocation strengthening, and effective load transfer from GO nanoplatelets. The findings demonstrate the potential of GO-reinforced Al5052 composites for advanced engineering applications, achieving significant mechanical property improvements through the ARB process.
