Effect of head treatment on the microstructure and mechanical properties of piston alloys

Abstract and figures

This research paper presents the results of the effects of heat treatment on the microstructure and mechanical properties of aluminum piston alloys. Four piston alloys of different chemical compositions were experimentally investigated. Different temperatures and times (480 °C to 515 °C for 1 h to 60 h) of the solution heat treatment were investigated. Additionally, the influence of the aging time and temperature (140–200 °C for 1 h to 30 h) on the hardness was studied. The results have shown that it is necessary to find the optimum combinations of the temperature and the time of heat treatment in order to achieve the required performance and economic savings. Keywords: piston, aluminum alloys, heat treatment
