Abstract
Aluminum alloys have been widely used for aerospace applications due to their high strength and lightweight. New demand is growing for aluminum alloys with high temperature mechanical properties that can sustain plastic deformation at high temperature. In this study, correlations among microstructure, tensile properties and Charpy impact properties were analyzed..... More
