We deal with a class of Penrose-Fife type phase field models for phase transitions, where the phase dynamics is ruled by a Cahn-Hilliard type equation. Suitable assumptions on the behaviour of the heat flux as the absolute temperature tends to zero and to are considered. An existence result is obtained by a double approximation procedure and compactness methods. Moreover, uniqueness and regularity results are proved as well.

The main focus in this paper is on homogenization of the parabolic problem . Under certain assumptions on , there exists a -limit , which we characterize by means of multiscale techniques for , . Also, an interpretation of asymptotic expansions in the context of two-scale convergence is made.
