A characteristic waiting time appears at fixed temperature above Tc or Ms for elements, alloys and polymers, where Tc is the usual first-order phase transition temperature and Ms is the normal martenstic phase transition temperature. This waiting time is called incubation time and related with the nucleation probability derived from a nucleation barrier. That is why nucleation process is regarded as thermal activated process at the non-equilibrium state. In particular, such a long incubation time of In-Tl alloys has a good agreement with experimental results by using Roitburd method. Furthermore, detailed and accurate experiments enable us to be aware that two dimensional growth occurs above Tp, where peculiar temperature, Tp, controls the time development of diffraction patterns and appears above Ms in this system.In contrast to soft phonon model, incubation time is essential property of the first-order phase transition and the key to resolve nucleation and growth process.
