and boron carbide (B4C) particles reinforced in 99.8% pure aluminum matrix mixed with 2%
graphite (Gr) is studied. Three different proportions of hybrid aluminium metal matrix
composite (HAMMC) are casted using the stir casting technique. The effect of percentile
variation of reinforcing particulate materials and solid lubricant are evaluated by
compression test, tensile test, micro-hardness, impact test and wear as per ASTM standards …
