“…Several literatures are available on the fretting fatigue behavior of various steels, Al alloys and Ti alloys. However, studies on the fretting fatigue behavior of heat resistant superalloys, more specifically, on the single crystal Ni-base superalloys are limited (Mall et al, 2010, Murthy et al, 2006. Previous studies on fretting behavior of engineering alloys have identified that the coefficient of friction (COF) is one of the primary variables which affect the fretting process (Dobromirski, 1992).…”

Fretting fatigue behavior of Ni-base superalloys used in gas turbine blades and disk assemblies have been investigated under ambient and high temperature conditions. A major emphasis was placed on the influence of experimentally measured tangential force coefficient on the fretting fatigue life prediction of a single crystal superalloy. Significant differences in the experimental fretting fatigue lives with respect to contacting superalloy combinations were found. These experimental findings were correlated with an analytical approach for the estimation of fretting fatigue life. The predicted results employing the crack analogue model provided good agreement with the experimental results. Also, the influence of secondary crystal orientation of single crystal superalloy on the frictional response and fretting fatigue life prediction was highlighted.

“…However, the use of shot peening at these elevated temperatures presented an improvement in fretting fatigue life of approximately 60%. Mall et al 12 investigated the fretting fatigue behavior of a nickel-base superalloy, IN100 at 600 C and concluded that plain fretting fatigue performance improved at 600 C in comparison to those at room temperature. Satoh et al 13 conducted fretting fatigue tests under various levels of contact pressure at room and elevated temperatures using 12Cr-Mo-W-V and 11Cr-Mo-V-Nb steam turbine steel.…”

Fretting fatigue behavior of Al 7075-T651 is investigated at temperatures of 20 ℃, 150 ℃, 250 ℃ and 350 ℃ and at different stress levels. The results show that: (a) fatigue life increases from 15% to 160% for low stresses and reduces from −20% to −40% for higher stresses and (b) fretting fatigue life increases from 155% to 290% for low stress levels and reduces from −12% to −65% for high stress levels. All life changes have been measured with respect to the lives at ambient temperature. It is believed that under low stresses, the effect of glaze oxide layer created through surface oxygen absorption prevails and gives rise to improvement of plain and fretting fatigue of material at elevated temperatures. Precipitation and solid solution hardening and good lubrication of the oxide layer are the main reasons for this improvement. For the higher stresses, 180, 200 and 280 MPa, the oxide layer breaks down and the degradation due to reduction in ultimate strength dominates the fatigue behavior of material and diminishes the fatigue lives. Fractography of specimens reveals brittle fracture mode in the fracture surface regardless of the test temperature. Optical microscopy of specimens shows more germination of precipitates at lower temperatures and shorter aging durations and more growth of precipitates for higher temperatures and longer aging durations.
