| titleOfInvention | Compacted powder article and method and apparatus for making same |
| abstract | A method for forming a high density body from a powder material of metallic and non-metallic compositions and combinations thereof comprising confining a quantity of the powder material in a compressible and expandable mold structure, subjecting the powder material in the mold structure to a predetermined pressure along one axis which confining the material against movement in directions normal to the axis so as to form a compacted body of the powder material and subsequently heating the compacted body to a predetermined temperature so as to further compact the body. A quantity of glass is heated so that it will flow and transmit pressure following which the heated body is immersed in the heated glass and the flowable glass is subjected to a pressure high enough to further compact the body. The resulting densified body is uniformly compressed in the directions of three mutually perpendicular axes extending through the body. The apparatus for forming the body includes a tubular member formed of foam material which is compressible in an axial direction and expandable inwardly in a radial direction so as to densify the powder material contained therein as a result of conventional piston and cylinder action in which the tubular member is contained within the cylinder and subjected to the action of the piston on one end. |
