Effects of quenching treatment on the structure and electrical property in doped V2O3 system

The effects of quenching treatment are examined in terms of the phase present, microstructure and electrical properties for doped V2O3 system, in this paper. The results indicate that the specimens transform to the PM phase and show microcracks in the structure after quenching. The room temperature (RT) resistivities become low and the resistivity ratios increase remarkably. There are optimum values for the RT resisitivity and resisitivity ratio under a certain quenching time. The electrical properties of quenched specimens containing Fe metal phase become stable after subsequent thermal cycles.
