Notes

Abstract: While ω precipitates in metastable β 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 ω containing β titanium alloys. LTA treatments, carried out on a
ductile β 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 (ε = 0.4 in true strain), resulting in a balance of mechanical properties.
