  • Ufa State Aviation Technical University (USATU)
    celebrated the 70 th anniversary in October 2002.

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

Titanium alloys for structural applications
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
9
Nanostructured Titanium for medical applications
Titanium possesses the highest
bio-compatibility Problem to increase strength
and fatigue properties Way to achieve
nanostructure formation
Compression- distraction apparatus
Plate implants
Screw implants for traumatology
