Superstrength of Nanostructured Ti Grade 4 with Grain Boundary Segregations

Superstrength of Nanostructured Ti Grade 4 with Grain Boundary Segregations

Severe plastic deformation and subsequent heat treatments yield nanostructured commercially pure (CP) titanium Grade 4 with average grain size of about 100 nm and exceptional strength. To elucidate the underlying strengthening mechanisms in this nanotitanium (nanoTi), this study uses atom probe tomo...
