Modelling of solidification and heat treatment for the prediction of yield stress of cast alloys

A model has been developed for the prediction of yield stress of cast alloys. It consists of integrated unit step models of the physical metallurgy of solidification, solid-state transformations, structural hardening and micro-mechanisms. Calibration of the precipitation and hardening unit step models is conducted based on experimental data available in the literature for aluminium–copper alloys. Applications are then carried out to study the …
