Mechanical Behaviour of Al7075 Hybrid Composites Developed through Squeeze Casting

The automotive and aerospace sector are behind the development of squeeze casting process, as the squeeze cast components exhibit improved mechanical properties. Squeeze casting is a hybrid metal processing technique that combines the advantage of both casting and forging in one operation. The aluminium alloy 7075 is a futuristic material that is widely used to produce automotive and aerospace components. Cylindrical component of AL 7075 was produced by varying the squeeze pressure at certain level. The specimen was made from the component as per ASTM standard and they were tested for mechanical properties such as tensile hardness and impact strength respectively. It was found that mechanical properties were enhanced with increase in squeeze pressure. The aluminium 7075 hybrid composites developed through squeeze casting is fabricated and experimented upon and found to have adequate potential for wide variety of application. In aerospace industries it can be used in gear components, blade sleeves, guide vanes, wing components etc. Applications in surface transport are brake rotors, automotive engine cylinder, engine exhaust valve, body chassis and connecting rods. This material can be used in light weight applications such as power lines and wind mill fans.
