Abstract
A process for preparing a consolidated nickel-base superalloy compact suitable for tensile force inducing high strain rate deformation. It includes the steps of: preparing a melt of a nickel-base superalloy in a vacuum; atomizing the melt into powder in a protective atmosphere; collecting the powder; screening the powder to proper size; introducing the powder into a container; evacuating and sealing the container in a vacuum; and consolidating the powder under pressure at a temperature below the solidus temperature of the alloy and at a temperature at which grain boundaries grow past prior particle boundaries.
