Fine-Grained Uranium by the Rotating Electrode Shot Process.

摘要

Particulate uranium with unusual grain structure is produced by the rotating electrode shot process (arc melting a rapidly rotating electrode) when the molten droplets are allowed to impinge on a cooled surface. The solidified product,designated as ''splat,''contains grains with a diameter below 10microns and an unresolved acicular structure. When consolidated by extrusion, splat has very fine grains;the extruded splat resembles cast and wrought uranium in other respects.
