A STUDY TO DETERMINE THE DEFORMATION CHARACTERISTICS OF BERYLLIUM AND TUNGSTEN UNDER CONDITIONS OF HIGH HYDROSTATIC PRESSURE
Abstract
Tensile and compressive tests under pressure were performed on specimens of sintered poly crystalline tungsten and beryllium. Results are presented as reduction in area versus pressure. A brittle-ductile field is mapped for tungsten from available data. Correlative fluid extrusions were performed on sintered poly crystalline tungsten and beryllium, and on a single crystal of beryllium. There were indications that crack-free fluid-to-fluid extrusions should be possible for all materials, with additional modes of deformation apparently activated at higher pressure levels. Analysis is presented on the role of pressure in plastic deformation, with extrusion to high-energy forming processes and to notch tensile testing.
