Abstract
Thermal-mechanical fatigue crack growth (TMFCG) was studied in a γ-γ’ nickel base superalloy Inconel X-750 under controlled load amplitude in the temperature range from 300 to 650°C. In-phase (Tmax at σmax), out-of-phase (Tmin at σmax) and isothermal tests at 650°C were performed on single-edge notch bars under fully reversed cyclic conditions.
A DC electrical potential method was used to measure crack length. The electrical potential response obtained for each cycle of a given wave form and R value yields information on crack closure and crack extension per cycle. The macroscopic crack growth rates are reported as a function of ΔK and the relative magnitude of the TMFCG are discussed in the light of the potential drop information and of the fractographic observations.
