The mechanical properties of Co-Cr-Mo-N alloys were investigated as a function of Cr and N contents for dental applications. 0.2% proof strength and ultimate tensile strength of N added Co-Cr-Mo alloys were higher than those of Co-Cr-Mo alloys. The mechanical properties were sensitive to N content, rather than Cr. It should be noted that plastic elongation of N added Co-33Cr-5Mo was higher than that of Co-33Cr-5Mo. It was considered that N contributed to the stabilization of the γ phase and the decrease of ε phase in the Co-33Cr-5Mo alloy.
