EFFECT OF DIE SLEEVE MATERIAL ON MECHANICAL BEHAVIOR OF A413 ALUMINIUM ALLOY PROCESSED THROUGH SQUEEZE CASTING ROUTE

Squeeze casting as liquid-metal forging process by which molten metal solidifies under pressure within closed dies positioned between the plates of a hydraulic unit. The main objective of this work is to investigate the mold, metal of molten metal contact during solidification with different controlled input variables such as squeeze pressure, die preheating temperature and melt temperature for different die sleeve materials. Absolute process variables produce a rapid heat transfer rate that yields a pore-free fine-grain casting with good mechanical behavior. In the cast samples, the mechanical behavior such as hardness and ultimate tensile strength were measured. From the work, it was ascertained that castings produced by copper die, sleeve have good mechanical behavior due to the faster solidification rate for this route.
