Strength is traditionally the key aspect of mechanical behavior of any structural material, including titanium alloys. Specific strength characteristics can be improved with the help of the increased strength rather than decrease of material density.

This work presents data on modification of ratio of such characteristics as σâ during tensile testing and τshear during double shear testing as a result of optimized heat treatment parameters for VST3553 and VST55531 alloys.

We performed the analysis of root causes of inverse dependence of τshear on σâ for VST3553 and VST55531 alloys as well as the review of factors influencing this inverse dependence.

This paper presents data on mechanical properties and results of cold bending of seamless cold-wrought tubes of VST3553 alloy.

This paper also contains properties of tubes made of VST2 and VST3331 alloys as compared with the properties of tubes made of classical alloys Gr9 and Ti6 Al4V.

Use of high-strength titanium alloys in applications where medium- and low-strength alloys have been traditionally used before, will help to significantly improve the performance of individual assemblies and also of the whole structure.
