The aim of this study was to investigate the effect of carbon concentration on microstructures and tensile properties of Co-33Cr-9W-0.34N-(0.01-0.31)C (mass%) cast alloys. The microstructures of the alloys primarily consisted of the γ (fcc) phase. The amount of carbide precipitates at the interdendritic region increased with increasing carbon concentration. Accordingly, the alloys exhibited higher yield stress (>600 MPa) than conventional Co-Cr dental cast alloys. On the other hand, elongation-to-failure showed a maximum (〜50%) at carbon concentrations of 〜0.1 mass%. The results of the current study can aid in the design of high-strength Co-Cr-based dental cast alloys.
