The high-temperature fatigue response of titanium and nickel alloys destined for high-performance gas turbine applications is considered with particular emphasis given to the role of creep and environmental damage during crack growth. In an attempt to partition the respective contributions from these two rate controlling factors, data are presented for a range of temperature, stress ratio, and pressure conditions. The implications for the extended use of such alloys in future gas turbine designs are discussed.
