Abstract
The commensurate - incommensurate phase transition in crystals in driv en by the nuclei called stripples. The stripple has a structure define d by the symmetries of crystal phases. It is nucleated as a result of thermal fluctuations. Since a macroscopic number of stripples is neede d to complete the phase transition a collective nucleation can take pl ace. There are two ideal mechaniscms of collective stripple nucleation s: cascade and serial ones. The stripple appearences are illustrated b y the results of mocelular-dynamics simulation on the model systems.
