Abstract

AA7075 is one of significant industrial aluminum alloys, its special mechanical properties such as strength and ductility has makes it used in varying applications. In this investigation a heat treatment process has been done after quenching in water in deferent temperatures and times, the mechanical properties (tensile strength & hardness) have been tested and the results have been designed by Taguchi method to predict the optimum strength and hardness values. The process parameters which a key role in deciding this study, were three tempering temperature (100,200,300) °C, three time holding (1,2,3)hr, three temperature rise rate (5,10,15) °C/min. Taguchi parametric design and optimization approach was used Minitab17 program to analyze the data find the optimal strength and hardness for improvement mechanical behavior of AA7075 aluminum alloy. The results found that optimum strength at parameters (100 °C, 5 °C/min, 1Hr) & the optimum hardness at parameters (100 °C, 5 °C/min, 2Hr).
