In order to examine the possibility of the high-Cr and high-N containing Co-Cr-Mo alloy for dental application, conventional dental casting was performed using the alloy and the micro structure and mechanical properties were evaluated in this study. Denture having mesh and clasp was successfully obtained. Typical dendritic structure with precipitates was observed in the alloy. TEM observation revealed that the stacking fault was distorted owing to the addition of Nitrogen. It was found that the high-Cr and high-N contained Co-Cr-Mo alloys showed higher plastic elongation compared to the conventional Co-Cr-Mo dental alloy.
