Modelling of precipitation in multicomponent alloys - Application to an industrial AA3003 aluminium alloy

摘要

The precipitation of dispersoids which occurs during the homo-genisation treatment of a multi-component alloy has been developed. This model describes the evolution of the particle size distribution as a function of time and temperature. In addition, the model is able to take into ac- count the variation of the overall solid solution composition by large scale diffusion in dendrite. Since it was developed for a multicomponent alloy, the precipitation of different phases can also be simulated at the same time.
