An attempt is made for the calculation of residual stresses due to nitriding in a component. The knowledge of the determinating processes and the evaluation of their influence on the residual stress state may assist the selection of the nitriding paramters for the optimization of the nitriding process. Special interest is laid on the description of the micromechanical effects occuring during nitriding. The following processes are considered within the model: * The creep behavior and plasticity, * the diffusion of nitrogen into the material, * the kinetics of the growth of nitrides, * the volumetric strains due to the interstitial nitrogen and the nitrides, * the transformation induced plasticity (here precipitation induced plasticity, PRIP) caused by the plastic accommodation process around the growing nitrides. The influence of all these processes on the residual stress state is studied for a cylindrical specimen.

The results are quantatively compared with measurements from the literature.
