Mechanical Properties of Multi Axially Forged Hybrid Composite

Abstract:

This work investigated the influence of multi axial forging (MAF) on the microstructure and mechanical properties of AA6063/Al₂O₃/Gr hybrid composite. It reveals that the effectiveness of forged composite exhibited better mechanical properties. The AA6063 reinforced with Al₂O₃ and 1 wt. % graphite (Gr) hybrid composite were fabricated using stir casting technique. The microstructure of the hybrid composite was examined using optical microscope. The mechanical properties in terms of hardness, flexural strength and compression strength were investigated. It was observed that the mechanical properties of multi axially forged hybrid composite exhibited around 15, 7 and 5 times higher than unreinforced alloy, as-casted hybrid composite and as-hardened hybrid composite. These results revealed that the multi axially forged hybrid composite would be well suited for high strength applications.
