ABSTRACT:
A process is described for producing forged ring articles from high strength, high temperature materials such as superalloys and titanium alloys. The material to be forged is conditioned and placed into a condition of low strength and high ductility. This starting material is then back extruded to produce a cup. The cup can be sliced into rings in which can thereafter be final forged to a particular contour.
