Originální abstrakt

Fatigue crack initiation and propagation was studied in cast polycrystalline nickel base superalloy Inconel 713LC in as-received condition and with surface treatment by AlSi protective coating. Cylindrical specimens were cyclically strained under strain control with constant total strain amplitude at 800 ?C. Fatigue fracture surface, specimen surface, and specimen sections were investigated using optical microscopy and scanning electron microscopy. Fatigue crack initiation sites and fatigue crack growth mechanisms were identified and crack propagation rates were obtained base on striation spacing in fracture surfaces. The crack initiation mechanism study revealed reasons for the fatigue life increase in the surface treated material.
