| The influence of cold drawing on the internal stresses (microstresses) developed in the ferrite phase of a pearlitic steel due to the plastic interaction of ferrite and cementite has been studied using X-ray technique. The microstresses were evaluated from experimental data by the method accounting for internal stresses caused by the ferrite plastic anisotropy (referred to as mesostresses). The main result is that microstresses in the ferrite phase gradually decrease down to near-zero level with increasing plastic strain. |
