Abstract
A Ni-based superalloy contains 13.1 to 16.0 percent by mass of Cr, 1.0 to 6.8 percent by mass of Co, 3.0 to 3.4 percent by mass of Al, 4.6 to 5.6 percent by mass of Ti, 2.0 to 4.4 percent by mass of Ta, 3.5 to 4.9 percent by mass of W, 0.1 to 0.9 percent by mass of Mo, 0.3 to 1.4 percent by mass of Nb, 0.05 to 0.20 percent by mass of C, and 0.01 to 0.03 percent by mass of B with the remainder being nickel and inevitable impurities. The superalloy excels in corrosion resistance, oxidation resistance, has high strength, and is used in parts of a gas turbine to be used at high temperature. The resulting gas turbine excels in durability.
