It is demonstrated that titanium and its alloys can be laser welded in an air atmosphere when they are cathodically protected under a flux of a high-temperature molten salt. This enables the development of a new titanium welding process that does not require shielding the work piece with an inert gas.

Deformation characteristics of Ti–6Al–4V
Materials Science and Technology, 1988AbstractThe deformation characteristics of Ti–6Al–4V have been established by torsion testing in the temperature range 800–1150°C. Constitutive equations are proposed for both the β-region and the α+β-region which, it is suggested, may have some practical applications.

Microplasticity in HCF of Ti–6Al–4V
International Journal of Fatigue, 2001Abstract Previous research has shown that Ti–6Al–4V exhibits pronounced stress ratio effects under high cycle fatigue (HCF) loading. At high stress ratios ( R >0.7), a transition of failure mode occurs from traditional surface fatigue crack initiation and growth to bulk-dominated damage initiation and coalescence of multiple microcracks consistent ...

We have studied fatigue characteristics of Ti-6Al-4V alloy synthethized by the simplest powder metallurgy technology including processes of pressing and pressure sintering of powder mixtures based on titanium hydrite. The powder material has relatively fine grains of /?-phase which, despite availability of residuale voids, provide quite high endurance ...

AIP Conference Proceedings, 2000
The shock behavior of a new Ti-6Al-4V alloy has been characterized up to stress levels of 13 GPa. Examination of velocity profiles obtained from five transmission experiments indicate elastic-plastic behavior in the material. Magnitude of the HEL lies between 2–3 GPa and appears to be dependent on material thickness.
