Numerical modelling of the aluminium extrusion process [PDF]

open access: yes
The extrusion of aluminium alloys involves the shaping of the product from an homogenised billet into a complex shape. In addition the properties of the extrudate are closely related to the processing parameters (temperature, stain rate, and material ...
