Solid solution strengthening effect by oxygen (O) and nitrogen (N) atoms of α-titanium (Ti) materials was quantitatively evaluated using Labusch model consideration the experimental data. When to predict solid improvement, an application isotropic strains solute elements is generally assumed estimate Fm value. It is, however, difficult exactly calculate value for α-Ti with O N because anisotropic are induced in crystal hcp structure these elements. In this study, experimentally derived from...
Intermediate α″ phase was constructed in as-printed Ti alloys by introducing interstitial carbon atoms to mitigate the detrimental effects of α′ martensite on ductility. The interstitials served as a lattice modulation limiter achieve an incomplete atomic shuffle during martensitic transformation process form metastable phase, followed stabilizing inhibit growth martensite. resulting microstructure, characterized dominant α/α′ matrix decorated with fine enhanced twinning formation ability...
Additively manufactured (AM) α+β titanium alloys produced by laser powder-bed fusion (L-PBF) typically exhibit fine acicular microstructures due to the intrinsically fast-cooling rates of process. In solute-rich such as Ti-6Al-4V, this extreme grain refinement can severely reduce plasticity (fracture strains < 10%), thereby exposing parts catastrophic engineering failures. pursuit a superior strength-ductility balance, we investigated L-PBF processing compositionally lean Ti-alloys...
Laser powder bed fusion (LPBF) titanium alloys are known to have a strong crystallographic texture; however, this is limited β-titanium alloys, while α-titanium usually show an acicular microstructure resulting from martensitic transformation. In contrast, <0001>//BD texture in CP-Ti was successfully formed by optimizing the LPBF conditions. study, we investigated mechanism of such formation through detailed microstructural analysis and experimental verification. It clarified that textured...
In this study, the particle collision treatments (fine bombarding (FPB) and conventional shot peening (SP)) were performed for Ti–6Al–4V alloy in order to comprehensively investigate influences of their treatment conditions on surface conditions, microstructures, hardness distributions residual stress. Moreover, we examined relationship between characteristics treated materials mechanical properties including fatigue strength detail. According obtained experimental results, values maximum...
