  • Material-technological modelling of the die forging of 42CrMoS4 steel = Materialno-tehnološko modeliranje utopnega kovanja jekla 42CrMoS4
    Pileček, Vít ...
    Material-technological modelling is a tool for effective designing and optimizing real-world forming processes. It involves processing a small volume of a material in a thermomechanical simulator ... under the conditions corresponding to those of the real-world process: in this case it was die forging. By means of modelling, the effects of changed parameters on the existing processes and products can be explored. The present paper presents the development of a highly complex material-technological model of real die forging of the 42CrMoS4 steel. The data required for developing this model were obtained during the production in a forge. The characteristics that are not technically measurable, such as the strains at particular points of the forging, were determined with the aid of a FEM simulation. Upon comparing the outcomes of the process modelling and the real schedule, the final microstructures including their phases and morphological characteristics were found to match. The microstructure consisted of a ferrite-bainite mixture. The discrepancy between the HV10 hardness levels of the specimen and the actual forged part was less than 2 %.
