Higher dimensional numerical simulations of precipitate dissolution in multi-component aluminium alloys

In thermal processing of alloys, homogenization of the as-cast microstructure by annealing at such a high temperature that unwanted precipitates are fully dissolved, is required to obtain a microstructure suited to undergo heavy plastic deformation. This process is governed by Fickian diffusion and can be modelled as a Stefan problem. In binary...

A suite of sharp interface models for solid-state transformations in alloys

A suite of mathematical models for solid-state phase transformations in solid-state alloys is presented. The work deals in particular with dissolution and growth of particles in solid-state alloys. Several models are presented and numerical solution procedures are summarized briefly. Further, some analytic solutions are considered shortly, which...
