Heat treatment is an essential process step in the final adjustment of the mechanical properties of the hardenable aluminium alloys. The effects of the precipitation hardening parameters on the mechanical properties of various aluminium alloys have been experimentally investigated, but the results are often incomplete or restricted to sub-steps of the heat treatment. In this work a time and cost efficient empirical method for predicting the mechanical properties of heat-treatable aluminum alloys on the basis of the precipitation-hardening conditions of the process steps solution annealing, quenching and ageing was developed. For the model, both the highest possible calculation accuracy and the speed of the model generation are important. Furthermore, the transfer of the method to components with different thicknesses and micro components was investigated. With this method it is possible to quickly calculate the mechanical properties of the known aluminium alloys as well as to quickly characterize of new alloys for the application in material development.
