Abstract

In the present paper, AGING heat treatment is used for optimizing the best WEAR property of Al-4Si alloys, in order to achieve this purpose, we added some Mg to that alloy during casting process, after homogenization, cast alloys were done solutionized at 540oC for 2 h, followed by water quenching (30oC) and artificial AGING at 180-240oC for 1-8hr, hardness and WEAR tests were conducted for as cast and heat treatment. A pin on disc type WEAR was used and load range of 5-30N was chosen. Scanning electron microscopy (SEM) of WEAR surface was carried to analyze the WEAR mechanism. Results show heat treating alloy have lower WEAR rate than the as-cast alloy and noticeable differences has taken in WEAR mechanisms which the main reason of this is due to broke down dendrite structure in heat treatment and leads to increase hardness and strength. The best WEAR property is achieved at 210oC for 8hr of AGING treatment. After WEAR X-RAY diffraction lines are broadened due to plastic deformation and increasing dislocation density in subsurface.
