Abstract
In order to improve the casting of high strength aluminum ingots, better understanding of mechanical properties of as-cast materials is important. Due to uneven cooling during the casting, the as-cast alloy shows inhomogeneous characteristics of microstructure which results in the variation of mechanical properties at different locations of an ingot. The mechanical properties of as-cast aluminum alloy 7050 were studied through the on-cooling tensile test, the fracture toughness test, and the quench cracking test. The results were correlated with the in-situ measured cooling history of a casting ingot and the microstructural parameters of as-cast Al 7050. They can be used to make the connection between the thermal field calculation and the stress field calculation in the casting simulation.
