Conserving Discretization for a Stefan Problem with an Interface Reaction at the Free Boundary. Modelling, Analysis and Simulation.

摘要

Heat treatment of metals is often necessary to optimize their mechanical properties. During the heat treatment, the metallurgical state of the material changes. This change can either involve the phases being present or the morphology of the various phases. One of these processes, which is both of large industrial and scientific interest and amenable to modeling, is the dissolution of second phase particles in a matrix with a uniform initial composition.
