Abstract
A specific set of criteria for the piston material is established by the piston’s actions and the loads acting on it. Pistons should be made of a low-density material if they are to weigh as little as possible. The load capacity of the piston is based on the strength of the material used in its construction in addition to its design shape. Static and dynamic robustness are both required because of the time-varying loads due to the high temperatures and resistance to heat. Aluminum alloy (M142) is ideally used as a piston material because it is a light alloy with high thermal conductivity. However, its power and wear resistance are insufficient in the unalloyed shape. In this research, an attempt has been made to reduce the weight as well as increase the power-to-weight ratio of M142 by adding magnesium (Mg) of 1.5%, 2%, and 2.5%, respectively. The test specimen has been prepared by gravity die casting way and the effect of Mg addition on M142 alloy mechanical properties namely tensile and hardness strength have been evaluated through Brinell and the tensile tester. This research also includes the microstructure analysis of M142 alloy by adding Mg at different amounts. It is confirmed from the research that the tensile and hardness of the material have been improved. The improvement in fatigue and ductility of M142 alloy has been revealed through the microstructure analysis.
