摘要: The thermodynamic nature of the massive transformation may be revealed by finding limiting conditions for mode growth. A review experimental information available indicates strongly that solvus line rather than theT0 is natural limit. Some observations inside two-phase field explained effect coherency strains in composition spike formed front interface. This has a significant thickness many cases and can explain role solvus. It exceedingly thin iron-base alloys, there higher diffusivity comparison made with γ Fe-M-C alloys where situation very similar.
