An attempt to explain the causes of retained austenite on the lattice transformation is undertaken. The lattice transformation in small fraction of the crystal produces the internal strain in the remaining austenite, which makes increase the resistance against the following transformation, but when the temperature of the crystal decreases, an excessive free energy to be able to overcome the resistance is stored by increasing in degrees of supercooling and then the transformation develops. In order to carry out a quantitative consideration of this phenomenon, in accordance with the fact that the lattice transformation resembles the plastic deformation in their crystallographic mechanism, we assume a relation between the free energy difference dissipated during the lattice transformation and the mechanical energy required for the plastic deformation. From this relation we evaluate the dependence of amounts of transformation on temperature through correspondence between the work hardening in plastic deformation and this phenomenon.
