Abstract
In order to characterize NiTi orthodontic wires microstructure, transformation temperatures, and deformation behaviour have been investigated. Various states of dislocation density were established by additional heat treatment of a work hardened material. The as recieved wire and the change in microstructure due to the chosen heat treatment were described by optical light microscopy. The stress induced transformation behaviour is related with the experimental results in transformation characteristic measurements and microstructural observations.
