Abstract

The process parameters and size of characteristic plastic values in aluminium hot extrusion technology are key points that influence product properties. The values in the temperature filed, the strain rate, elements of stress tensor of aluminium alloy AA6005 is investigated according to different process conditions. The software simulation was accomplished in the commercial FEM package FORGE2008 to calculate both the scalar values evolution as well as the tensor values during the forward extrusion process.
