HEAT-RESISTANT Ni-BASED ALLOY AND METHOD FOR MANUFACTURING SAME |
| 摘要 |
The present invention is a heat-resistant Ni-base alloy including a Ni—Ir—Al—W alloy having essential additive elements of Ir, Al, and W added to Ni, wherein the heat-resistant Ni-base alloy includes Ir: 5.0 to 50.0 mass %, Al: 1.0 to 8.0 mass %, and W: 5.0 to 20.0 mass %, the balance being Ni, and a γ′ phase having an L12 structure disperses in a matrix as an essential strengthening phase. The heat-resistant material including the Ni-base alloy may contain one or more additive elements selected from B: 0.001 to 0.1 mass %, Co: 5.0 to 20.0 mass %, Cr: 1.0 to 25.0 mass %, Ta: 1.0 to 10.0 mass %, Nb: 1.0 to 5.0 mass %, Ti: 1.0 to 5.0 mass %, V: 1.0 to 5.0 mass %, and Mo: 1.0 to 5.0 mass %, or 0.001 to 0.5 mass % of C. |
