Influence of Wire Geometry on the Mechanical Behavior of the TiNi Design

The present article is aimed at studying the deformation behavior of TiNi wire and knitted metal mesh under uniaxial tension revealing role geometry on their main mechanical characteristics mechanisms behavior. temperature dependence curve electrical resistance indicates that a two-stage martensitic transformation B2→R→B19′ occurring, responsible for superelasticity effect. TEM results showed room temperature, has nanocrystalline structure composed B2 austenite grains. A change in mechanism was established tension, where exhibits effect superelasticity, while made from this characterized by hyperelastic Fracturing requires significant loads up to 3500 MPa compared fracture load wire. With wire, which maximally repeats mesh, an increase observed.
