Formation of Topologically Closed Packed Phases in Nickle Base Single . . . With this increase in complexity comes an increase in the difficulty of predicting and controlling the formation of topologically close packed (TCP) phases These phases have long been associated with property reduction assites forcrack initiation, or simply by robbing the matrix of solid solution strengthening alloying elements Inmany
Formation and effect of topologically close-packed phases in nickel . . . The formation of topologically close-packed (TCP) phases in nickel-base superalloys is an issue of increasing importance as alloys are designed with higher refractory element contents to meet the requirements of next generation turbine engines
Effect of Alloying on Topologically Close - NASA Technical Reports . . . Ni-base superalloy single crystals represent the state-of-the-art for turbine engine airfoil application as they offer the best balance of properties to allow for the high operating temperatures required for efficient engine operation 1 Current trends in alloy design take advantage of improved creep rupture strength with the addition of higher
