Abstract SPD techniques as ECAP proces can be used for non-forrous metals like Ti, Cu, Mg, Al, etc. to change its properties. It was approved that elvated temperature provide a succefully conditions for the fine grained final materials obtaining. This paper was aimed on verification of functionality of the ECAP technology at extrusion of the Ni-Ti alloys. This article deals with method of continuous change of resistivity as function of temperature of Ni-Ti alloys, and with influence of deformation and subsequent heat treatment at these temperatures. Circular cross-section of original samples was 12 mm in diameter and their length was 50 mm. For the samples of Ni-Ti alloys was used the two-stage pressing, when the samples were extruded at temperature of approx. T1 = 773 K and T2 = 723 K. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was approximately determined. After individual passes there was occurred an accumulation of deformation strengthening (???= 745 Mpa). Microstructure depends on experimental conditions, particularly on number of passes and on rotation of the sample between individual passes.
