Deformation behaviour of low-alloy steel 42CrMo4 in hot state
Original language description
For reasons of the comprehensive study of deformation behaviour of this steel in the hot state, a whole set of torsion tests was carried out on the plastometer SETARAM. From the results of continuous tests to rupture the characteristics of dynamic recrystallization were evaluated; the start of the dynamic recrystallization is defined by coordinates of the peak stress. These values were then used for determination of the activation energy in hot forming by means of the specialized software ENERGY 4.0. Formability of the studied steel could be represented, on the basis of results of torsion tests, by the 3D graph in relation to temperature and strain rate. The performance of the anisothermal interrupted torsion tests was used for the evaluation of phasetransformations in the steel and these phase transformations were afterwards confronted with the decomposition diagrams designed by the dilatometric tests and by means of software QTSteel. The diagrams were executed in two modes (CCT and
