A quasistatic evolution problem for a phase transition model with nonconvex energy density is considered in terms of Young measures. We focus on the particular case of a finite number of phases. The new feature consists in the usage of suitable regularity arguments in order to prove an existence result for a notion of evolution presenting some improvements with respect to the one defined in ``Fiaschi A., A Young measure approach to a quasstatic evolution for a class of material model with nonconvex energies'', for infinitely many phases.
Keywords: Young Measures, phase transitions, rate-independent processes
