Abstract
The purpose of this study was to obtain pure nanostructured titanium by drawing at cryogenic temperatures and to investigate its structural and mechanical properties. Titanium rods were obtained by severe plastic deformation under the scheme of upsetting‐extrusion‐drawing. Upsetting and extrusion were performed at 800 K, obtained rod was initially drawn at 300 K to diameter of 3.7 mm (degree of true strain ε = 3.2). Further deformation of the finish drawing was performed at 77 K (liquid nitrogen) and at 300 K.
