Abstract: A novel program for supporting design of a gamma dash precipitation strengthened platinum group element-added Ni-based superalloy. To support the design, a computer is allowed to function as input means (1) for inputting the composition, use temperature, and use stress of an Ni-based superalloy, storage means (2) for previously storing the constituent elements of the Ni-based superalloy, the structure factor calculation formula thereof, and the alloy characteristic calculation formula thereof, structure factor calculating means (3) for calculating the structure factor from the alloy composition by using the structure factor calculation formula read from the storage means (2), alloy characteristic calculating means (4) for calculating an alloy characteristic from the alloy composition, the structure factor, the use temperature, and the use stress by using the alloy characteristic calculate formula read out of the storage means (2), and output mean (5) for outputting the structure factor and alloy characteristic together with the alloy composition. Therefore, alloy characteristic analysis and alloy composition search of a gamma dash precipitation strengthened platinum group element-added Ni-based superalloy are simply, easily, and efficiently conducted. A design supporting device therefor is also disclosed.
