Abstract:

Physical simulations were performed to identify and validate material models, which are used in optimization of manufacturing chains of fasteners. The focus was on hot rolling and controlled cooling. Physical simulations of thermomechanical processes were performed to validate microstructure evolution model for hot forming. Multi-stage deformations in the plane strain compression test were performed on the Gleeble 3800 simulator. Dilatometric tests were performed to identify and validate phase transformation model. Microstructure was investigated after each test using optical and electron microscopy. Good predictive capability of the models was confirmed.
