A new single crystal (SC) superalloy TMS-82+ which contains only 2.4% Re has been developed by using a computer aided alloy design program (ADP) developed in the National Institute for Materials Science (NIMS). The compositions were designed as follows; a large negative lattice misfit at operated temperature, 60 vol.% of γ, solution heat treatment window of >50°C, and creep strength better than 2nd generation superalloys. Corrosion resistance was also considered. A brief explanation of the NIMS-ADP and the whole development works of SC alloy TMS-82+, such as alloy selection, metallurgical and mechanical tests, a full-scale production test and an engine test in the 15MW gas turbine, will be described here.
