| Description
| - Material-technological modelling is a tool for effective designing and optimization of real-world forming processes. It involves processing a small volume of material in a thermomechanical simulator under conditions corresponding to those of the real-world process: in this case this was die forging. By means of modelling, the effects of changed parameters on existing processes and products can be explored. In addition, modelling can offer insight into the properties and microstructure of an intended final product during development of new technologies. The present paper introduces the development of a highly complex material-technological model of a real-world part from 42CrMoS4 manufactured by die forging. The data required for developing this model were measured during production in a forging plant. These data sets comprised temperature and strain values with respect to time. Characteristics which are not technically measurable, such as strains at particular points of the forging, were determined with the aid of FEM simulation. Building on these data, the material-technological model of the entire process was developed, including the heating and cooling stages. Material-technological modelling was carried out in a thermomechanical simulator. Upon comparing the outcomes of the process modelling and the real-world schedule, the final microstructures, including their phase and morphological characteristics, were found to match. The microstructure consisted of ferrite-bainite mixture. The discrepancy between HV10 hardness levels of the specimen and the actual forged part was a mere 4 %.
