Prediction of Microstructure and Mechanical Properties in Aluminium Castings after Heat Treatment

Abstract:

A comprehensive numerical model has been developed for the calculation of the final microstructure and mechanical properties of aluminium casting alloys after heat treatment. The calculation is chained in such a way that the resultant microstructure of the previous processing step, such as casting, is used as the initial condition of the following step. In this paper an A357 alloy is chosen to study the microstructure and the evolution of the mechanical properties through the process from casting to heat treatment. The microstructure and mechanical properties are predicted and compared with experimental measurements.
