Abstract
Designing processes for producing responsible structural elements from steel in the hot forging process requires knowledge of the relationship between the process parameters, the microstructure that is formed under the assumed deformation conditions as well as the quality and properties of the forgings. The analysis of the microstructure after deformation allows the identification of phenomena occurring during hot processing, such as work hardening, recovery and recrystallization. On this basis, it is possible to determine both favorable sets of deformation parameters and to identify their combinations that lead to the risk of microstructural defects. However, during multi-stage open-die forging on hydraulic presses, the deformation rate does not change significantly, but the temperature gradually decreases during subsequent operations. Then, if necessary, the temperature is raised to the upper limit during intermediate reheating. As a result, the process is often carried out over a wide temperature range and cannot be maintained within a favorable temperature range. Selected results of comprehensive tests were presented, which were aimed at controlling the state of the microstructure and, therefore, the properties of forgings made of 80MnSi8-6 steel shaped in multi-stages. This goal was achieved by analyzing and controlling subsequent stages of the forging process, paying particular attention to the quality of the shape. To perform this research task, numerical modeling using the finite element method and forging tests in laboratory conditions were used.
