Abstract

The study deals with the evaluation of tensile properties of eutectic, hypereutectic and super eutectic aluminium alloy under various heat treated conditions. Pistons are produced from cast or forged, high-temperature resistant aluminium silicon alloys. There are three basic types of aluminium piston alloys. The standard piston alloy is a eutectic Al-12%Si alloy containing in addition approx. 1% each of Cu, Ni and Mg. Special eutectic alloys are also evaluated for improved strength at high temperatures. Hypereutectic alloys with 18 and 24% Si provide lower thermal expansion and wear, but have lower strength. The tensile and impact properties are evaluated for all the conditions of eutectic, hypereutectic and special eutectic aluminium alloys. The experimentation is carried on a bench tensometer and on Izod and Charpy Impact testing machine. The properties are evaluated for various heat treated conditions like operating temperature, quenching conditions, annealing conditions. It is concluded that based on the impact and tensile properties, type of material can be selected as the piston material.
