Abstract
Plastic deformation of stochiometric NiTi in the martensitic state was investigated. Four structural conditions were established until a dis ordered a phase is formed by very high amounts of deformation. Changes of the course of martensitic cycles and R phase formation were analys ed, until transformability clases at epsilon > 40%. Thermally activate d reactions are able to recreate martensitic retransformatibility in t he highly deformed condition.
