Effect of Alloy Composition on Microstructure and Tensile Properties of Net-Shaped Castings of Al–Zn–Mg–Cu Alloys

In this study, the effect of alloy composition on uniaxial tensile properties of Al–Zn–Mg–Cu alloys was investigated using seven distinctive alloy compositions. The sample alloys were manufactured as net-shaped components using the controlled diffusion solidification technology coupled with the tilt pour gravity casting process. The effect of T4 and T6 heat treatment on the castings was investigated using seven alloy compositions with the total …
