EXTRUSION OF METAL BY HIGH PRESSURE LIQUID.
Abstract
An experimental method of metal extrusion by high-pressure liquids is reported. In the preliminary experiments ten liquids were liquids were tested as pressure-transmitting media for the extrusion of AD1 commercial-grade aluminum (99.3% Al, 0.75% Fe + Si + Cu). The results of these experiments are presented. Water produced the best results. Extrusion pressures for a number of metals and alloys are presented. Extrusion by liquid requires a much lower pressure than extrusion by conventional methods; high-pressure liquid extrusion of aluminum with 90% reduction requires 4500 kg/sw cm, compared to 18,000 kg/sq cm for the conventional method. Extrusion with high-pressure liquid also improves mechanical properties. (Author)
