Gibbs molar volumetric energy and iron boundary are determined depending on temperature. It has been shown that phase transformations in occur under thermodynamically equilibrium conditions. The microcrystals dendrites. Crystallization of the melt is a nanostructural process. Iron recrystallization to be largely diffuse

About 70% of all the steel compositions that are currently used have been developed within the last 10 years. Novel iron alloys are being conceived, manufactured, and marketed with a regularity which has confounded many prophecies. Phase transformation theory has contributed to the successful development of steels. This overview will begin therefore with a discussion of the atomic mechanism by ...
