摘要：
A process is disclosed for producing a sheet of tungsten heavy alloy which involves uniformly blending elemental powder components of the alloy by forming a slurry of the powder components in a liquid medium, removing the liquid medium from the powders and forming a planar cake of the powders, drying the cake, sintering the cake to a density equal to or greater than about 90% of the theoretical density of the alloy to form the sheet.
