Abstract

A process for making a workpiece suitable for being hot worked to produce a wrought metal poduct is described. Aluminum alloy powder is cold compacted and then heated in an inert environment to provide a sinter-sealed shape. The resultant workpiece may then be subjected to conventional processing to produce the desired wrought product.
