Abstract: 

The ASTM F-75 (Co-28%Cr-6%Mo) is widely used as a biocompatible alloy in medicine for manufacturing implants. In this study, effect of mold preheating on the as-cast microstructure of the alloy was investigated using the solid investment casting process. Several mold preheating temperatures of 550, 700, 850 and 1000 °C were selected at the same melt superheat. The samples were characterized by optical microscopy, electron microscopy and macro-hardness test. The results showed that the size of grains and secondary carbides of the matrix was increased by increasing the mold preheating temperature. In addition, morphology of the M23C6 carbides was changed from the eutectic carbides precipitated in grain boundaries to the blocky shape precipitated in both carbide interface and dendritic matrix. The appropriate microstructure with nearly fine grains with homogeneous distribution of secondary phases was obtained at mold preheating temperature of about 850 oC.
