Abstract

The paper deals with the surface roughness of extruded aluminum alloy products and the direct observation of the contact conditions at the tool-metal interface by means of a specially designed extrusion tool which can be easily split along the tool-metal interface. Particular attention is given to the reduction of friction between the metal and the tool surface and to obtaining products with very smooth surfaces.
