TA15 titanium alloy is widely used in aerospace industry in terms of its high specific strength,
good thermal stability, and excellent corrosion resistance. To further improve its mechanical …

Thanks to many fascinating properties, such as high mechanical properties, good corrosion
resistance, and excellent biocompatibility, beta-type Ti alloys are frequently employed as …

Limited slip systems of α structure always play a major role in hindering strength-ductility
synergy improvement of titanium (Ti) alloys. To overcome the strength-ductility trade-off of Ti …

In conventional duplex titanium (Ti) alloys, the soft primary α-precipitates (α p) are beneficial
to ductility with the loss of high yield strength, while the continuous α-precipitates at grain …

Develo** fine-grained high-strength titanium (Ti) alloys by additive manufacturing has
boomed interest for both research and application. The eutectoid element addition has been …

Abstract β Ti-alloys can achieve a high strain-hardening rate and tensile ductility by taking
advantage of transformation induced plasticity (TRIP) and twinning-induced plasticity (TWIP) …

A multiscale dislocation-based model was built to describe, for the first time, the
microstructural evolution and strain-hardening of {332}⟨ 113⟩ TWIP (twinning-induced …

It is well accepted that grain-boundary phases in metallic alloys greatly deteriorate the
mechanical properties. In our work, we report on a novel strategy to prepare high strength …

Metastable β titanium alloys usually suffer from relatively low yield strengths, which restricts
their applications as a structural material. Additive manufacturing (AM), due to its extremely …
