THE EFFECTS OF HIGH HYDROSTATIC PRESSURE ON SUBSEQUENT PHYSICAL PROPERTIES OF METALS

Abstract

Studies were made of the changes in the physical properties of metals after the metals were treated at high hydrostatic pressure (200,000 psi maximum) for periods up to 3 weeks. Treated and untreated samples of polycrystalline Mg and Al were tested in te sion. No observable changes in strength properties occurred in either metal as a result of pressure treatment. Ductility of Mg was reduced slightly, but the effect is attributed to slight plastic deformation rather than to the pressure treatment itself. X-ray diffraction was used to study changes in single crystals of Al. No definite conclusions were drawn from the results because of low precision in the data. The x-ray studies are being continued to obtain more consistent results. (Author)
