Initial nucleation kinetics of martensite transformation
- 250 Downloads
The initial rate of martensite transformation in Fe–Ni and Fe–Ni–Mn is described by the product of the probability of a nucleation site existing in an austenite grain times the probability of its propagation. The former depends on driving force, the latter on defect mobility. The onset of both athermal and isothermal martensite could be modeled in a consistent way, which suggests that both modes have common fundamentals.
