Abstract
A thermomechanical process for producing high strength and thermally stable alloys, comprising the steps of: pre-heating an alloy bar or rod stock of a pre-selected size at a temperature below that at which grain growth occurs; and thereafter rotoforging the heated alloy bar or rod stock at a sufficient deformation level and temperature to fragment the grain boundary phases of the alloy. The resulting alloy is characterized by an ultra-fine, very uniform grain size, high tensile strength at room and high temperatures, good ductility, and a stress-rupture rate that is about twice as long as conventional alloys that have not undergone the thermomechanical process.
