In this study, we systematically investigated the influences of nitrogen content and grain size
on the tensile properties and deformation behaviors of titanium at room temperature. By high …

Although stress-induced martensitic transformation accelerates grain refinement during
plastic deformation, it results in serious damage to recoverable elasticity and ductility of …

This paper reports an ultrafine-grained Ti–24Nb–4Zr–8Sn–0.4 O (wt.%) alloy produced by
warm rolling at 673K, showing notable nonlinear elastic deformation with a recoverable …

According to Considère necking criterion, enhancing strength of a material will decrease its
elongation to failure, ie ductility, even if the strain hardening rate remains unchanged …

Interstitial solutes (eg O, N) often enhance strength; however, their poisoning effect leads to
markedly decreased ductility and even embrittlement in titanium (Ti) alloys. Thus, using …

A dehydrided Ti powder of very high oxygen content was successfully consolidated using
back pressure equal channel angular processing into a fully dense bulk ultrafine-grained Ti …

High specific-strength lightweight titanium (Ti) alloys, in the absence of interstitial
strengthening of oxygen (O) atoms to avoid O-embrittlement, are mainly strengthened via …

Ultrafine-grained (UFG) metals exhibit excellent mechanical strength and high hardness at
room temperature; however, most have negligible work-hardening ability. In this study we …

Optimizing strength and ductility by uniting microstructural heterogeneity and profitable
crystallographic orientation is a challenge due to processing difficulties. Here, we synthesize …

Severe plastic deformation of commercially pure titanium, leading to ultrafine-grained
microstructure, can be used as an alternative to alloying to obtain better mechanical …
