Since gas turbines are used in airplanes, ship engines and power plants, they play a
significant role in providing sustainable energy. Turbines are designed for a certain lifetime …

Thermomechanical fatigue in distinct crystal orientations of nickel-base single-crystal
superalloy was studied. Crack initiation modes and damage mechanisms were …

Within the gas turbine engine, the high transient thermal stresses resulting from throttle
movement from idle to high settings give rise to the phenomenon of thermo-mechanical …

Understanding of crack growth behaviour is necessary to predict accurate fatigue lives. Out-
of-phase thermomechanical fatigue crack propagation tests were performed on FB2 steel …

In-phase TMF crack growth testing with different lengths of the hold time at the maximum
temperature of 550° C has been conducted on Inconel 718 specimens. Focus has been on …

The crack driving mechanisms in a coarse grained nickel-base superalloy RR1000 when
subjected to in-and out of phase thermo mechanical fatigue are investigated. It is found that …

Exploring crack growth behaviour is needed to establish accurate fatigue life predictions.
Cracked specimens were tested under strain-controlled out-of-phase thermomechanical …

In this paper, a crack opening stress equation for in-phase and out-of-phase
thermomechanical fatigue (TMF) loading is proposed. The equation is derived from …

Non-isothermal conditions during flight cycles have long led to the requirement for thermo-
mechanical fatigue (TMF) evaluation of aerospace materials. However, the increased …

Isothermal fatigue (IF) of polycrystalline nickel based superalloy Inconel 718 was studied to
reveal the effects of microporosity and TCP phase on the damage mechanisms and fatigue …
