Evaluation of mechanical properties of 1060-Al reinforced with WC particles via warm accumulative roll bonding process

In the present study, aluminum metal matrix composites (AMMCs) reinforced with tungsten carbide (WC) particles are manufactured through warm accumulative roll bonding (ARB). The composite microstructure shows excellent WC particle distribution in the Al matrices, and no reaction between Al and WC is observed. Compared with the ARBed 1060-Al, the Al/WC composites show a higher number of dislocations, as suggested by the introduction of WC particles. The tensile, hardness, and wear properties of the Al/WC composites are determined. The introduction of 3 vol% WC particles to the Al matrix via the warm ARB process leads to significantly enhanced mechanical properties.

► WC particle is first used to reinforce AMMCs via ARB. ► Al/WC composites consist of ultrafine grains and numerous dislocations. ► Excellent mechanical properties of Al/WC composites are exhibited. ► Wear property of particle-reinforced AMMCs fabricated via ARB be evaluated firstly.
