Description
Summary:The Improvement of mechanical properties of Al-9Zn-5Cu-4Mg cast alloy by T5 Heat treatment 200 °C during 200 hours was studied. Al-Zn-Cu-Mg alloy can be used in wide range of aircraft industry is based on the superior characteristic of this alloy. The main objective of this study is to investigate the influence of ageing process by performing tensile and hardness tests. The results revealed thatagingprocessisaffecting to the deployment of precipitationand it is indicate the formation of second phases MgZn2 by atomic reactions that lead to the change of mechanical properties of Al-9Zn-5Cu-4Mgcastalloy..
