“…Deformation-induced refinement is one of the main trends in the production of bulk metallic nanostructured materials which can be implemented using severe plastic deformation (SPD) [1]. Despite the existence of complicated SPD schemes (e.g., equalchannel angular pressing, isothermal forging, screw extrusion, and others [1][2][3]), we have shown for the first time that SPD, which can be used to create nanostructural materials, can be achieved by a sequential combination of deformation techniques that provide different stress epures (compression-squirting-extrusion-drawing) [4][5][6][7][8][9]. Deformation by drawing carried out at the final stage under cryogenic conditions (77 K) is an additional and important factor in structural refinement.…”

The structural state of iodide titanium after deformation by drawing at 77 K, which is the final stage of severe plastic deformation (SPD), has been analyzed and estimated in this work. The SPD has been implemented by a sequential combination of deformation techniques (compression-squirting-extrusion-drawing) that provide different stress epures. The temperature dependence of the logarithmic damping decrement of torsional oscillations in the 77-250 K temperature range has been studied to give a physical interpretation of the nonmonotonic change in the strength of the iodide titanium after SPD and to compare the calculated strength with that obtained for low purity titanium.

“…By the manufacture of superconducting Nb-Ti wire, the most important stage is cold drawing with the area reduction of the original bar Ø60 …70 mm→Ø0.1…1.0 mm [8]. As-produced superconducting wire is expected to have high strength resistance to breaking as well as structural uniformity, i.e.…”

Using atomic force, optical and electron microscopy methods, the changes in the microstructure and phase composition were investigated for the alloy Nb47%Ti used for the manufacture of superconducting cable employed as current-carrying elements in the magnetic system for International Thermonuclear Experimental Reactor. The test samples were prepared from the superconducting wire at an intermediate step of the drawing process for the area reduction Ø1.3→Ø1.2 mm. The effect of cold drawing and intermediate annealing on the properties of as-worked Nb-Ti alloy was assessed. Local strain zones were found to occur in the rupture area. The shape and chemical composition of Nb-Ti wire was examined for both a defect-free area and the rupture area. A Nb diffusion barrier was found to occur in the copper matrix of NbTi wire.
