Microalloying as a key strategy to maximize the strength–ductility combination in dilute titanium alloys Open
A highly effective microalloying strategy for titanium hardening is presented. The main idea of this approach is to activate a novel strengthening mechanism, i.e. precipitation strengthening with nanoscale β particles located inside the α …

Decoding the interstitial/vacancy nature of dislocation loops with their morphological fingerprints in face-centered cubic structure Open
Dislocation loops are critical defects inducing detrimental effects like embrittlement and swelling in materials under irradiation. Distinguishing their nature (interstitial- or vacancy-type) is a long-standing challenge with great implica…

Microstructure evolution and deformation mechanisms during compression of a harmonic–structured Ti–24Nb–4Zr–8Sn alloy Open
Processing heterogeneous microstructures, especially the so-called harmonic structures consisting of soft core and hard shell regions, is an efficient way to achieve a strength-ductility trade-off in classical metallurgy. In this study, tw…

First experimental evidence of oxygen ordering in dilute titanium–oxygen alloys Open
Small addition of oxygen is currently used to improve the mechanical properties of titanium. It has been thought, until now, that oxygen fully dissolves in the titanium matrix, thus leading to a solid solution. However, we show here, with …

A review of the metastable omega phase in beta titanium alloys: the phase transformation mechanisms and its effect on mechanical properties Open
Since its discovery in 1954, the omega (ω) phase in titanium and its alloys has attracted substantial attention from researchers. The β-to-ω and ω-to-α phase transformations are central to β-titanium alloy design, but the transformation me…

Polymorphic nature of {332} 〈 113 〉 twinning mode in BCC alloys Open
Unprecedented mechanical properties of the novel TWIP/TRIP titanium alloys are controlled by {332} twinning and stress-induced martensitic transformation, which can operate separately, simultaneously or even in synergy, following a still u…
