Abstract : EFFECT OF HYDROSTATIC PRESSURE ON THE PLASTICITY OF METALS: Increase under pressure; Rupture of steel; Rupture of nonferrous metals; Area of the existence of linear dependence of the true deformation in rupture under pressure; Mechanical properties of metals under presures up to 39,000 kg/sqcm- equipment; CONDITIONS OF THE OUTFLOW OF METALS FROM THE ORIFICE OF A DIE IN THEI EXTRUSION BY A LIQUID UNDER HIGH PRESSURE: Two extrusion methods; Procedure; Role of the liquid medium; Surface quality; Speed; PressureDeformation relationship; Effect of die inlet angle size; Comparison of force systems (High pressure liquids vs plungers); Distribution of the deformation over the cross section of extruded rods. MECHANICAL PROPERTIES OF METALS EXTRUDED BY A HIGH-PRESSURE LIQUID: Mechanical properties of metals deformed under high hydrostatic pressures; Research procedure; Influence of deformation; Influence of pressure. TECHNOLOGICAL POSSIBILITIES OF THE EXTRUSION OF PARTS FROM METALS BY A LIQUID UNDER HIGH PRESSURE: Extrusion of parts with a complicated profile, and tubing; The hydraulic compressor.
