Hot and cold shaping of materials by a fluid at superhigh pressure
This article examines technological aspects of the use of superhigh-pressure fluids for the hot extrusion, cold extrusion, and compaction of powders at pressures up to 2000 MPa. New methods for the hot extrusion and hot compaction of powders by superhigh-pressure fluids are described. Some results are presented from use of the new technology of shaping materials with superhigh-pressure fluid.
