Abstract
Microscopic fibers are mixed with a metal powder to provide a nonuniform mixture with randomly oriented fibers having metal particles adhered thereto. This mixture is extruded at room temperature at least three times, and is then placed in a die cavity and subjected to a first pressure at room temperature. While adding no additional pressure, the die cavity is heated to bring the mixture to a temperature above the solidus of the metal powder, and the volume of the die cavity is decreased to at least the theoretical volume necessary to receive the mixture if the mixture included no voids. The die cavity is then cooled and the resultant billet ejected therefrom.
