Enhancement of aluminium alloy (AL7075) composite by the addition of crs particle via stir casting technique

In this research, we added crushed rock sand (CRS) particles to an Al7075 matrix material, and composites were fabricated through a stir-casting approach. The reinforcement percentage varies from 0% to 12% by weight in discrete increments of 3%. Physical and mechanical parameters such as hardness, ultimate tensile strength, and impact toughness and corrosion performance by the gravimetric method, as well as tribological properties such as specific wear rate and coefficient of friction (COF), were tested at both ambient temperature ([Formula: see text]C) and elevated temperature ([Formula: see text]C). The density of the developed composite samples has been substantially lowered with an intensification in wt.% of CRS particles. The mechanical parameters of the developed composite samples have been considerably enhanced with an intensification in wt.% of CRS particles. The 9[Formula: see text]wt.% CRS-reinforced samples have an outstanding incrementation percentage of 52.44% hardness, 24.85% tensile strength, and 19.90% impact toughness. Better corrosion resistance is observed for the 9[Formula: see text]wt.% sample. Similarly, the same sample shows a 28.06% increase in specific wear rate at [Formula: see text]C and a 43.35% increase at [Formula: see text]C.
