摘要

Abstract

BSTRACTWhile

precipitates in metastable

titanium alloys are typically considered embrittling and consequently deleterious to the mechanical properties

this paper demonstrates that low-temperature aging (LTA) treatments for short time periods can in fact enhance the yield strength while preserving substantial elongation-to-failure in

containing

titanium alloys. LTA treatments

carried out on a ductile

metastable Ti–12Mo alloy

significantly improve the yield strength of the material (∼55% increase as compared to solution-treated samples) while keeping both TRIP/TWIP effects and a large elongation-to-failure (

= 0.4 in true strain)

resulting in a balance of mechanical properties.

IMPACT STATEMENT

Employing a novel low-temperature annealing strategy

omega precipitates

typically considered embrittling in beta titanium alloys

can effectively increase the yield strength by 50% while preserving 40% tensile ductility.
