Abstract
A thermal mechanical treatment method includes consolidating a powder by a severe plastic deformation process and ageing the consolidated powder at low temperature. The method may include cryomilling the powder before consolidating the powder by a severe plastic deformation process; hot isostatic pressing the consolidated powder into a dense powder before aging the consolidated powder; hot extruding the dense powder into a stock shape before aging the consolidated powder; hot-working the stock shape on a gyrating forge at a predetermined temperature before aging the consolidated powder; or heating the consolidated powder to a predetermined temperature, and maintaining the consolidated powder at the predetermined temperature for a predetermined time.
