| Sumario: | In this project, the effect of the addition of magnesium and lithium in the aluminum alloy for foundry A380 was investigated, where the mechanical properties and the process of friction stir welding (FSW - Friction Stir Welding) in the alloys were analyzed. The alloys were machined to obtain specimens of tension and hardness, and the plates were welded by means of the FSW process with a heat treated AISI 1045 steel pin, varying only their geometry. For the microstructure analysis, light microscopy and scanning electron microscopy were used, the chemical composition analysis was carried out by means of spark spectrometry and the intermetallics formed by means of EDS were observed. The results show a reduction in density of up to 11.35% compared to the A380 alloy, but likewise a reduction in its mechanical properties. |
