A process for producing a wrought product of improved ductility from substantially noncompactible prealloyed metal powder. The process comprises the steps of: comminuting substantially noncompactible prealloyed metal powder so as to flatten the particles thereof; heating the comminuted particles of metal powder at an elevated temperature, the particles adhering and forming a mass during heating; crushing the mass of metal powder; compacting the crushed mass of metal powder; sintering the metal powder; and hot working the metal powder into a wrought product. The wrought product has a chemistry which is substantially the same, with the exception of carbon and certain residuals, as the chemistry of the prealloyed powder. |
