Local Atomic Mechanism for the Diffusion Jump of Carbon Atom in Austenite
A carbon atom diffusion jump in iron austenite was considered as a subsequence of
transformations between the cementite structure and the regular FCC packing. A model of this
transformation was based on a 2D model of the elemental act of a polymorph transformation
in metals. The energy threshold of this transformation has been calculated using the Morse
pair potential. It occurs that the estimated enthalpy of the transformation is equal to 149±20
kJ/mole which is in satisfactory agreement with experimental data
