Abstract
Present study was carried out to investigate the mechanical properties of newly developed cast aluminum alloy with addition of copper 1.0 % (at.) and magnesium 1.0 % (at.) in the mole ratio of 1:1:1 Al-Cu-Mg. The selection of Cu-Mg on the basis of stoichiometric calculations, 0.55 (at. %) of copper and 0.21 (at. %) of magnesium were mixed in liquid aluminium base material, which was prepared in electric furnace. The melt was held at 750 ºC with alloying additions of copper and magnesium for about 5 min to ensure complete homogenization. Further, this liquidous aluminium metal matrix was stirred at 500 rpm for 5 min and poured at 700 ± 10 ºC in permanent mild steel mould at 200 ºC in order to achieve as-cast alloy. Solution treatment at 500 ºC for 1 h and thermally aged at temperature 160 ºC for 5 h was exposed. The effect of solution and thermal aging temperature on metallurgical morphology and the role of intermetallic compounds on mechanical properties of as-cast alloy have been studied. The optical microscopy and scanning electron microscopy equipped with energy dispersive spectroscopy were used to identify the intermetallic phases and formation of different precipitates was studied by using X-ray diffraction. The improvement in ultimate tensile strength and hardness values have been reported.
