ResumoIn order to investigate the multi-variable friction phenomenon during aluminium and magnesium extrusion, tribological experiments with the alloys AA6060 and AZ31 against hot working steel 1.2344 were carried out. Using a new a xial friction test, the effects of the normalized normal stress (1.5-6), the temperature (300 °C - 500 °C) and the relative sliding speed (0.1 - 50 mm/s) were investigated. The influence of each parameter on the friction behavior is analyzed, the friction results are depicted and a modified Tresca friction model is developed.
