Surface refining of Al-Si alloy was carried out using the GTA heat source. It was observed that the microstructure contains a globular shaped eutectic - Si distribution within the α- Al matrix. The hardness is found to increase and the wear is found to decrease upon surface refining. The precipitation hardening treatment was effective in increasing the hardness of the modified layer. The GTA heat source has been successfully applied to the surface refining of the Al-Si alloy. The result of this study is in agreement with those of previous studies. © (2014) Trans Tech Publications, Switzerland.
