Fatigue crack propagation in nickel-base superalloys:effects of microstructure, load ratio, and temperature

King, J.E. (1986). Fatigue crack propagation in nickel-base superalloys:effects of microstructure, load ratio, and temperature. Materials Science and Technology, 3 (9), pp. 750-764.

Abstract

The current state of knowledge and understanding of the long fatigue crack propagation behavior of nickel-base superalloys are reviewed, with particular emphasis on turbine disk materials. The data are presented in the form of crack growth rate versus stress intensity factor range curves, and the effects of such variables as microstructure, load ratio, and temperature in the near-threshold and Paris regimes of the curves, are discussed.
