Abstract : The patent relates to a billet-forming process and apparatus. This includes selecting a hollow tube of thin-walled construction and having a relatively enlarged, interior chamber-passage or hole, partially filling the interior chamber-hole with loose metal powders, evacuating and heating the tube to eliminate substantially all air, moisture and gas particles from the interior hole thereof, sealing off the tube into an air-tight condition, and deforming the tube to squeeze together the metal powders into a solid mass of a predetermined approximate porosity in direct proportion to the amount of the simultaneous reduction occurring in both the outside and inside, hole diameters of the tube as a result of the controlled deformation thereof.
