METHODS OF PROCESSING METASTABLE BETA TITANIUM ALLOYS

摘要

A method of processing a metastable beta titanium alloy comprising solution treating the alloy at a solution treatment temperature that is above the alloy's beta transus temperature (Tβ) before cooling; aging the solution treated alloy by heating the alloy at a heating rate of 10°C per minute or lower to an aging temperature that is 90 - 110°C less than the Tβ and holding the alloy at the aging temperature; deforming the aged alloy at a deformation temperature that is at or below the aging temperature; and annealing the deformed alloy by heating the alloy to an annealing temperature that is at or above the Tβ.
