摘要

The ability to design metal forming processes requires knowledge of continuum mechanics and materials engineering. The papers presents the results of research on the complete analysis of the forging process of microalloyed steel. The forging process assessment was performed based on thermomechanical calculations and using microstructural modeling. Hardness tests were employed for the verification of computed results. A method of predicting the relation between quality of final product and history of metal forming as well as microstructural development using an FEM simulation is also presented here. The results of the FEM-simulation for the forging process and material are compared with experimental data to show the feasibility of the proposed method. Finally, it is stated that by using properly built software it is possible to eliminate brittle cracking in the forged products, especially at low temperatures.
