HIGH STRENGTH SINGLE CRYSTAL SUPERALLOY |
摘要 |
A nickel-base superalloy for single crystal casting of components exhibiting excellent creep and rupture properties at high temperature and stresses, and which exhibits excellent phase stability contains 5.60% to 5.80% by weight of aluminum; 9.4% to 9.8% by weight of cobalt; 3.2% to 3.9% by weight of chromium; 7.8% to 8.5% by weight of tantalum; 5.3% to 5.7% by weight of tungsten; 0.50% to 0.70% by weight of molybdenum; 4.3% to 4.9% by weight of rhenium; 0.75% to 0.90% by weight of titanium; 0.08% to 0.15% by weight of hafnium; less than 1.1% by weight of tramp elements other than aluminum, cobalt, chromium, tantalum, tungsten, molybdenum, rhenium, titanium and nickel; and balance nickel. |
