Abstract
The present invention relates to a NiIr-base heat-resistant alloy which includes a Ni—Ir—Al—W-base alloy which contains Ir: 5.0 to 50.0 mass %, Al: 1.0 to 8.0 mass %, W: 5.0 to 20.0 mass %, and the balance is Ni, and a γ' phase having an L1structure precipitating and dispersing in a matrix as an essential strengthening phase, and a ratio (Y/X) of a peak intensity (Y) of (201) plane of the IrW phase observed in the range of 2θ=48° to 50° to a peak intensity (X) of (111) plane of the γ′ phase observed in the range of 2θ=43° to 45° in X-ray diffraction analysis is 0.5 or less. The alloy exhibits good high-temperature property stably.
