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 …

A multi-alloyed near β-Ti alloy Ti-6Cr-4Mo-2Al-2Sn-1Zr (Ti-64221) with high strength and
high ductility was designed utilizing the d-electron theory combined with molybdenum …

High energy input additive manufacturing (AM) such as wire-based directed energy
deposition technologies are capable of high deposition rates but can result in coarse …

New theory is presented to describe the occurrence of plasticity-induced transitions in
titanium alloys. The approach is able to predict the composition dependence of …

In this paper, we have obtained metastable β Ti-4V-2Mo-2Fe (at.%) alloys with exceptional
mechanical properties through the control of grain size. The microstructure analysis reveals …

The evolution of the ω phase and its role in plastic deformation in a twinning-induced
plasticity β Ti–12 V–2Fe–1Al alloy aged at 373–573 K have been studied in this work. The …

The high pressure torsion (HPT) of various binary Ti alloys with β-stabilizers (Fe, Co, Ni, Mo,
Nb) was studied. Before HPT, the samples were annealed and contained (i) pure β …

A metastable β titanium alloy, Ti–2Al-9.2 Mo–2Fe (wt.%), with athermal ω phase after
quenching has been subjected to high strain rate (∼ 3000 s− 1) compression at ambient …

This paper reports a new {315} α ″type deformation twinning system, in adition to {130}<
310> α ″in a full α ″Ti-23Nb (at.%) alloy. The {315} α ″twins were identified by trace …

The strength-elongation to fracture (ε f) trade-off and low strain hardening rate have been a
longstanding dilemma in titanium alloys. In this work, we innovatively manufactured a novel …
