A theoretical model is formulated to describe solid state eutectoid transformation. Solutions incorporating appropriate boundary conditions are derived for transient and steady states. It is shown that the transient solution describes build up of the interfacial boundary layer, whereas the steady state solution extends into the phase. The presence of this boundary layer with considerable concentration and temperature gradients sug gests a solid state analogue to constitutional super cooling, as in the liquid to solid transformation.
