Abstract

Solution Treatment is the process of heating the material and cooling it with a fast cooling rate. The solution treatment process with rapid cooling can cause dislocations, so it is necessary to carry out the aging process. This study aims to smooth the coarse primary silicon structure and eliminate dislocations on the surface of the piston material and also to determine the hardness of the material and the density of the material through solution treatment with variations in aging temperature. The method used in this study is a direct experiment with AC8A aluminum solution treatment at a temperature of 490 0C for 1 hour then quenched with water cooling media. The material resulting from the solution treatment was observed for microstructure, density and hardness. Then the material is subjected to an aging process with variations in aging temperatures of 125 0C, 150 0C and 175 0C holding time for the same 30 minutes. After completion, observations of microstructure, microstructure with the smallest crystal grain size occurred in the aging process with a temperature of 150 0C. Density value or the highest density occurs in the aging process with a temperature of 150 0C. The highest hardness value occurs in the aging process with a temperature of 175 0C.
