Abstract

It is shown that the friction stir welding (FSW) is one of the most effective welding processes for retention of the fine-grained microstructure in Al alloys. The starting material used is an Al alloy 1050-O with chemical composition as Al-0.10Si-0.29Fe-0.01Cu-0.02Mg-0.01Zn-0.02ti. The average grain size is about 40 micrometer and the hardness value is approximately 21 Hv.
