Effect of cooling rate on the incubation period of time temperature transformation curve;

In this paper choosing the Mo-Al system,by the idea of plotting the solid state phases,the evolvement of the incubation period and species of primary phase of interfacial reaction products are introduced during Mo-Al solid-solid interfacial reactions from the related theory and experiment,respectively.

The bainite incubation period,during isothermally holding or aging in testing steels and β copper base alloys after solution treatment,is a process,in which,due to solute atoms diffusion and segregation at the crystal defects and at〈001〉crystal directions in the parent phase,distinct regions of solute enrichment and solute depletion are formed.
