Description:

In this study, novel Ni–Co base disksuperalloys were designed based on a combination of Ni-base blade superalloy TM-47 and Co-12.5 wt.% Ti, both of which possess a γ–γʹ two-phase structure. First screen results using single crystal casts revealed TM-47 to be a potentially promising candidate as a base alloy for Ni–Co base disksuperalloy, while additions of Co-12.5 wt.% Ti to TM-47 was found to improve creep strength of the alloy.
