title: The influence of carbon content on the mechanical properties in a cast dental Co-Cr alloy.
abstract: By varying the amount of acetylen in acetylene-oxygen flames Co-Cr test pieces with a varying carbon content were produced. The hardness, yield point for 0.05 per cent, 0.1 per cent and 0.2 per cent tensile strength and elongation were determined for these test-pieces. The results showed that hardness, yield points and tensile strength increased with increased carbon content, whereas the elongation lessened. The clinical importance of the altered mechanical properties due to increased carbon content in the Co-Cr alloy under study was discussed.
