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.
