Abstract: Cast Al – Cu- Mg alloys have been widely applying in aircraft and aerospace industries since many years due to their extraordinary mechanical properties like super strength and super strength-to-weight ratio. In this research an intensive investigations have been made on their mechanical behaviors and microstructural changes due to casting magnesium and copper with mother Aluminium cast. The hardness profile indicates the great effect of magnesium and copper when doped with Aluminium cast. Heat treatment for 2 hours at 3800C has been conducted for observing the mechanical properties changes and microstructural also. The effect of Magnesium and ageing on microstructure was analyzed by Scanning Electron Microscope (SEM) and optical microscope. Moreover, the chemical compositions were determined using Optical Emission Spectroscopy (OES) and EDS analysis.
Keywords: Aluminum-Copper-Magnesium Alloys, Effect of Magnesium, Heat Treatment Effect, Microstructural Changes.
