Modeling Phase Transformations

This section describes how to model metallurgical solid-solid phase transformations. When you simulate processes such as hardening of steel, these phase transformations are fundamental because they ultimately determine the final properties of the material. In the phase transformation interfaces, each phase transformation is defined by a certain evolution equation that defines the time rate of change of the algebraic proportion of a destination phase at the expense of a source phase. In the following, the two modeling concepts of phases and phase transformations are discussed.
