A mathematical model and computer simulations for predicting the response of aluminum casting alloys to heat treatment

Abstract

In this publication we report on our efforts to develop a mathematical model and the necessary material database that allow predicting physical and material property changes that occur in aluminum casting alloys in response to precipitation-hardening heat treatment. We use the commercially available finite element software ABAQUS and an extensive database that was developed specifically for the aluminum alloy under consideration - namely, A356.2 alloy. The model produces multiple outputs at each node including the thermal history of the component that develop in the component and mechanical properties.
