THE INFLUENCE OF THE THERMAL TREATMENT ON THE MICROSTRUCTURE AND FRACTURE FEATURES OF NiTi ALLOY

Popis výsledku v původním jazyce

The aim of this work was to study the influence of thermal treatment of the NiTi alloy on the microstructure, fracture features, and phase composition. NiTi sheets with a thickness of 2 mm and a chemical composition of 56.3 wt% Ni and 43.7 wt% Ti were used for the experiment. The samples were subjected to solution treatment at 850 oC for 1 hour and subsequent aging at 450 oC for 1 hour, or only aging at the same temperature and time for the as-received state of the material. All steps were finished by water quenching. Experiments were carried out for four states of the samples, namely the as-received state, after solution treatment, solution treatment and aging, and only aging. The study of the microstructure was carried out using a transmission electron microscope. The samples were tensile tested at a strain rate of 6.67.10-5 s-1 and the fracture surfaces were examined using a scanning electron microscope. Phase composition was estimated using XRD analysis.
