Abstract
The invention relates to the area of deformation and thermal treatment of titan-nickel alloys featuring the shape memory effect and can be used in mechanic engineering, medicine and technology. The method is proposed to produce nanostructured titan-nickel alloys (with grain size below 100 nm) featuring the shape memory effect. The method consists of thermal and mechanical treatment that involves combined deformation and annealing. Deformation is performed in two stages, the first stage consisting of intense plastic deformation by means of Equal Channel Angular Extrusion (ECAE) within the temperature range of 300 – 550°C, the cumulative true deformation ratio (ε) to exceed 4, while the second stage involves a setting deformation with deformation degree of at least 30% at the temperatures of 20 – 300°C; annealing is performed at the temperatures of 200 – 400°C.
