The mechanical behaviour of Fe-C alloys have been determined in their phase transformation ranges during isothermal or anisothermal transformations. Two models an analytical model and a finite element model have been used in order to calculate the behaviour of the material. Considering a macroscopic scale, these models show that the mechanical behaviour can be well described when an additional deformation, i.e. the transformation plasticity deformation, is considered.
