SYNTHESIS AND CHARACTERIZATION OF AL-CU-MG ALUMINIUM ALLOYS AND STUDY THE EFFECT OF DEFORMATION AND AGING ON THEIR PROPERTIES

Abstract: The binary alloy of Al-Cu and ternary alloys of Al-Cu-Mg was developed. The effect of magnesium content on microstructure and mechanical properties of Aluminium-copper-magnesium alloys was examined for different weight % of Magnesium. Rolling and Full annealing of Al-Cu-Mg Aluminium alloys was carried out. Comparison of microstructures and mechanical properties with different deformation rates and aging time was also done and its effect on properties of Al-Cu-Mg Aluminium alloys was analyzed. These properties were then compared with the properties of AlCu5 alloy which underwent the most optimum heat treatment cycle.

Keywords: Al-Cu-Mg alloys, heat treatment, cold-working, aging, strength, hardness.
