Creep-fatigue behavior of NiCoCrAlY coated PWA 1480 superalloy single crystals [PDF]
Single crystal specimens of a Ni base superalloy, PWA 1480, with a low pressure plasma sprayed NiCoCrAlY coating were tested in various 0.1 Hz fatigue and creep fatigue cycles both at 1015 and 1050 C.

Effect of variable load on crack initiation microalloyed steel S 690-QL
Metalurgija, 2015 The accumulation of damage in the form of initiation and growth of micro-cracks is the first stage of destruction that ends when the merger microcracks form macro cracks. Cracks formed in the cycle number N =104 - 105 are the result of low cycle fatigue.
