    摘要: An airfoil having a melting temperature of at least about 1500°C and comprising a first piece (12) and a second piece (14) joined by a braze (16) to the first piece (12). The first piece (12) comprises one of a first niobium-based refractory metal intermetallic composite and a first molybdenum-based refractory metal intermetallic composite, and the second piece (14) comprises one of a second niobium-based refractory metal intermetallic composite and a second molybdenum-based refractory metal intermetallic composite. The braze (16) joining the first piece (12) to the second piece (14) comprises one of germanium and silicon, and one of chromium, titanium, gold, aluminum, palladium, platinum, and nickel.
