Effect of heat treatment on mechanical properties of Co–29Cr–6Mo–0·33C superalloy

Abstract Investment cast Co–29Cr–6Mo–0·33C alloy tensile test specimens were subjected to heat treatment at 1230°C under argon atmosphere for different times to ascertain what enhancement of tensile properties could be achieved by such processing. Improvements in tensile properties were observed in the 2 h annealed specimen. Also, tempering of this specimen at different times shows that tensile properties and hardness increase and exceed those of the ASTM specification. However, elongation decreases during tempering. The annealed specimen has better corrosion resistance in comparison with as cast specimen.
