Extrusion pressures and velocity fields were determined for inverted extrusion processes of commercially pure lead. The extrusion ratios were varied from 1.51 to 18.5 (33.7 per cent to 94.6 per cent reduction). It was found that, for both low and high friction at cylinder wall and at die surfaces, qualitative agreement exists between slip-line solutions and experiment.
