Deformation behavior of shape memory alloys on ECAP process

Popis výsledku v původním jazyce

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 subsequentheat 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 defor
