THE COMPRESSION AND DEFORMATION OF LEAD SPHERES IN THE UNIRAM TETRAHEDRAL ULTRAHIGH PRESSURE DEVICE,

Abstract

Small, lubricated lead hot was placed in close packed layers in the UniRam and pressed to 52 kilobars pressure. The lead spheres were deformed into dodecahedrons which revealed the uniformity of compressive and flow mechanisms in tetrahedron samples. The results indicate that overall uniformity is chiefly dependent upon alignment and symmetry of sample and anvils. Also indicated is that extruded webs are established from material along the edges and corners of the sample tetrahedron early in the pressurization cycle and that such samples would be best when preformed with webs in place.
