Title: Yield stress and plasticity of nanostructured titanium of different purity at 300, 77, and 4.2 K

Specimens of nanostructured titanium with different dopant concentrations were prepared by intense plastic deformation via equal-channel-angular pressing. The low-temperature mechanical characteristics of the specimens subjected to active deformation under uniaxial tension and compression were studied. The yield stress and the limit uniform deformation of nanostructured and coarse-grained polycrystalline titanium were compared.
