Originální abstrakt

High temperature low cycle fatigue behavior of the cast nickel-based superalloy Inconel 713LC in as-received condition and coated with an Al-Cr diffusion layer have been investigated. The diffusion coating was deposited using the CVD out of pack technique. It was characterized and the hardness depth profile was measured. Fatigue tests were performed at 800 C in air using cylindrical specimens. Cyclic hardening/softening curves, cyclic stress-strain curve and fatigue life curves were obtained. The detrimental effect of the surface treatment on the Manson-Coffin and the derived Wöhler curves is documented. Fracture surface and surface relief observations and examinations of specimen sections help to discuss the effect of the diffusion coating on the fatigue life.
