Abstract
A process is disclosed for producing a sheet of tungsten heavy alloy which involves forming a solution of chemical compounds containing the metal values of the alloy in the correct proportion as in the alloy, crystallizing the compounds from solution and drying the compounds, reducing the compounds to their respective metals wherein each particle is an admixture of the allow components; forming a slurry of the metals and a liquid medium, removing the liquid medium from the metals and forming a planar cake of the metals, drying the cake, and sintering the cake to a density equal to or greater than about 90% of the theoretical density of the alloy to form the sheet.
