Effect of annealing on the hot salt corrosion resistance of the fine-grained titanium alpha-alloy Ti-2.5Al-2.6Zr obtained via cold Rotary Swaging [PDF]

arXiv
A hot salt corrosion (HSC) test was performed on the fine-grained titanium alpha-alloy Ti-2.5Al-2.6Zr (Russian industrial alloy PT-7M). The ultrafine-grained (UFG) microstructure in the titanium alpha-alloy was formed via cold Rotary Swaging. The grain size and volume fraction of the recrystallized microstructure in the alloy were varied by choosing ...

Design and Rate Control of Large Titanium Alloy Springs for Aerospace Applications

Aerospace
During the separation between satellite and launch vehicles, large steel springs are often used as compression separation spring sets in a catapult separation system. Replacing the steel springs with titanium alloy springs could reduce weight by about 50%

Shear Melting and High Temperature Embrittlement: Theory and Application to Machining Titanium [PDF]

arXiv, 2016
We show that alloying with rare earth metals (REMs) can dramatically improve the machineability of a range of titanium alloys, even though the REM is not incorporated in the alloy matrix. The mechanism for this is that under cutting, shear bands are formed within which the nano-precipitates of REM are shear mixed.

Strengthening strategy for a ductile metastable β-titanium alloy using low-temperature aging

, 2017
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 ...
