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
