Hybrid aluminum composites obtained with stir casting were investigated in this study. Aluminum alloy EN AW 6061 was reinforced with particles of Al2O3 and walnut-shell ash (WSA). The weight fraction of Al2O3 was constant (5 w/%) and for the walnut-shell ash, it was (1, 2 and 3) w/%. The morphology of the composites and particle distribution were e...

In this work, the stir casting method was applied to obtain composites based on the alloy AN EW 6061 used as a metal base, and Al2O3 particles as a reinforcement. Composites play a significant role as engineering materials. Therefore, it is necessary to study, in detail, the production methods and the factors that affect their mechanical properties...
