NUMERICAL AND EXPERIMENTAL INVESTIGATION OF COLD ROTARY SWAGED TI ALLOY

Popis výsledku v původním jazyce

The aim of our study was to investigate the cold rotary swaging on the Ti6Al4V alloy with a finite element modelling (FEM) and subsequently by experimental verification of the model predictions. The experimental examination was evaluated both cast and swaged material states. A FEM analysis was performed to describe the rotary swaging from a 7.5 mm round bar diameter with the total reduction of 27 % in cross-section. The numerical simulations were focused on the investigation of swaging force, distributions of strain, stress state, temperature and plastic flow of material. Subsequent experimental verification such as microhardness, tensile properties, and microstructure observations validated the predicted results. The one of experimental analysis was dedicated on measurement of swaging force during RS by using KOMAFU S600 dynamical force measuring system. After comparison between predicted and experimentally obtained data a good agreement was found. Among others there was observed same trend between microhardness profile and imposed strain distribution throughout the cross section of swaged billet.
