Abstract

The results of numerical modeling of direct and indirect extrusion process of a model alloy of high strain-rate sensitivity at room temperature, Sn38Pb, are presented. The studies were carried out for three values of die angle, three temperatures, four ram speed values, two values of extrusion coefficient and two values of friction factor. Effect of extrusion process parameters on distribution of effective strain, effective strain rate in extruded bar and extrusion load was estimated.
