Abstract

Combinations of deformation, aging, and reversion heat treatments have been investigated as a basis for improving the strength and ductility of beta-stabilized titanium alloys. Suitable control over the volume fraction of the omega phase in the ß-III alloy results in enhanced yield strength combined with some ductility. Deformation of the beta phase in the quenched ß-III alloy promotes bi-modal precipitation of the alpha and omega phases. The stability of the fine alpha particles maintains high strength with some improvement of ductility after the omega phase has been reverted.
