Abstract Metastability-engineering, eg, transformation-induced plasticity (TRIP), can
enhance the ductility of alloys, however it often comes at the expense of relatively low yield …

Improving the room temperature (RT) strength/ductility and hot-working capacity based on
lamellar microstructures is of great significance for the practical application of TiAl alloys …

Excessive interstitial oxygen (O) contamination, usually causing a dramatic loss of ductility,
remains a longstanding challenge for titanium (Ti) and its alloys. Here, we propose to solve …

In this study, for the first time, the evolution of geometrically necessary dislocation (GND) and
statistically stored dislocation (SSD) densities, as well as their roles in strain hardening …

Abstract Nowadays, Ti–Nb–Ta–Zr (TZNT) alloy have attracted attention as new titanium alloy
material for surgical implant applications due to its biocompatibility, great corrosion …

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 …

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 …

In this study, we propose a novel defect engineering strategy for circumventing the strength–
ductility trade-off of a β-type Ti–35Nb–7Zr–5Ta alloy and discuss its underlying mechanism …

The strategy of heterogeneous-structured (HGS) high manganese steels was designed by
asymmetrical-rolling (AR) with annealing to obtain superior mechanical performance for …

In this study, a design strategy employing stress-induced β to hexagonal α′ martensitic
transformation to develop a novel Ti-15Nb-5Zr-4Sn-1Fe alloy with ultrahigh strain hardening …
