  1. Ufa State Aviation Technical University (USATU) celebrated the 70 th anniversary in October 2002. Bulk Nanostructured Metals from Severe Plastic Deformation Ufa State Aviation Technical University 12, K.Marx str, Ufa, 450000 Bashkortostan RUSSIA Phone/Fax: 7-3472-569693E-mail: root@admin.ugatu.ac.ru

  2. Institute of Physics of Advanced Materials (IPAM) The institute was founded in 1995. The main scientific field includes development and research of nanostructured materials. Our stuff consists of 35 employees. 4 Professors and 5 Ph.Drs are among them. High pressure torsion ECAP die-set TEM

  3. High pressure torsion method a) b) Typical nanostructures of CP Ti (a) and Ti –64 (b).

  4. Equal Channel Angular Pressing ( ECAP) method 350 nm a) b) Typical nanostructures of CP Ti (a) and Ti –64 (b).

  5. 1 st stage – ECAP routes A- without rotation; Bc- clockwise rotation 90°; Ba- counter-clockwise rotation 90°; C- clockwise rotation 180° Image of the samples  20-60 x 100-200 mm

  6. The technological route of cold rolling: (1) - billet; (2) - rolls. 2 nd stage- cold rolling 3 13  16 R 15 11.5-0.2 12 1 2 2 12 1 1 2 2 1 1 The technological route of cold rolling: (1) - billet; (2) - rolls. The technological route of cold rolling: (1) - billet; (2) - rolls.

N Material Mechanical properties -1, Nf Titanium alloys for structural applications US, MPa YS,MPa , % , % MPa 1 Coarse-grained 460 400 27 60 255 4211 2 Nanostructured 820 800 15 60 400 34504 The important requirement for structural materials is combination of high strength, ductility and fatigue properties. One of the most perspective way here is the fabrication of nanostructures in commercial alloys. High-strength fasteners CP Titanium fatigue limit (-1) and number of cycles to failure (Nf) of fasteners
