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.

Abstract Air oxidation behaviour of a Ti–6Al–4V alloy was examined over the temperature range of 600–800 °C for different time intervals ranging between 0.5 and 72 h. In addition to the determination of the oxidation kinetics by weight gain measurements, oxygen diffusion zone (ODZ) depth and hardness measurements were conducted on the cross-sections ...

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 ...

ABSTRACTTitanium and many of its alloys show very poor wear resistance considering their hardness. This together with high thermodynamic driving forces to form very hard compounds between titanium and nitrogen or carbon made titanium based alloys obvious candidates for ion implantation.

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 ...

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.

The yield stress of materials exhibiting work‐hardening and thermal softening can reach a maximum, at which they are unstable to further strain. Deformation then localizes as shear bands. This critical strain has been calculated using parameters for the Steinberg‐Guinan strength model.
