Effect of alloying element on microstructure and mechanical properties ofCoCrMo alloy for Orthopedic Application

CoCrMo-۰.۶ Ti and CoCrMo alloys were cast using a Vacuum Induction Melting furnace. The effect ofTi addition on the microstructure and mechanical properties of samples was studied. Results showed Ti additionled to the formation of TiC precipitates and consequently, an increase in hardness from ۳۱۱ HV to ۴۰۶ HV, anincrease in tensile strength from ۶۴۷ MPa to ۷۱۵ MPa, and a decrease in elongation from ۱۳% to ۹%.
