Processes severe plastic deformation of powder materials. The purpose of the work. receive theoretical framework to manage the process of creating nanostructured states in alloys such VT1-0. The method of investigation. Experimental study. Theoretical study. Mathematical modeling. Results. Established that the deformation of titanium is initially via twinning; Further evolution of structures associated with the development substructure and deformation vysokokutovyh borders. The mechanisms of formation of fine-grained structure of samples in different parts of the intensive plastic deformation. There was a problem of insufficient grinding structure around the axis of strain; availability of this problem is explained not high enough angle screw channel matrix asked to resolve in the next stages of research. Presence stationary structure under given parameters of temperature and hydrostatic deformation. This structure is characterized by the size of the fragments and provides an ideal material ductility. The processes of forming the metal form its own limit structure. It is established that the intensity of the fragmentation process depends not only on temperature and speed conditions of deformation and the magnitude of hydrostatic pressure, but also on the degree of deformation, load path and velocity gradient tensor deformation and rotation. The conclusions that limit the structure of a metal is likely to shape the processes at the same level of pressure lead to a meaningful reduction in ductility. To ensure that the nanostructure of these processes must take place at sufficiently high pressure. In this case, the relaxation of internal stress is by fragmentation of crystallites. Projected use of results of operations. The results can be used to develop technology for new materials with improved performance for medical use.
