| Abstract: | Influence of cold drawing and annealing treatments upon pseudoelasticity of NiTi wire with 49.8% Ni has been examined. It was shown that complete pseudoelasticity and different pseudoelastic characteristics were observed over a temperature range up to 45 K under varying cold drawing and annealing conditions. Excellent pseudoelasticity can be obtained in Ti 49.8%Ni wire annealed at 723 K for 30 min after 39% cold drawing reduction. |
