Original abstract

Cylindrical specimens of Inconel 713LC in as-cast condition and with Al diffusion coating by the CVD technique were cyclically strained under total strain control at 800 degC. Hardening/softening curves, cyclic stress-strain curves, and fatigue life curves are obtained. The coating has a beneficial effect on the Manson-Coffin curve while the fatigue life is reduced in the Basquin representation. The stress response of the coated material is lower in comparison with the uncoated one. Sections parallel to the specimen axis have been examined to study fatigue damage mechanisms.

Práce se zabývá studiem vlivu vrstvy Al na únavové chování (únavovou životnost) lité polykrystalické niklové superslitiny Inconel 713LC při vysoké teplotě 800 stC v režimu řízené deformace na vzduchu. Byly sledovány změny mikrostruktury, měřena tvrdost, dokumentovány křivky změkčení/zpevnění, cyklická napěťovo – deformační křivky, křivky únavové životnosti. Na základě lomových ploch a osových řezů byly také studovány mechanismy únavového poškození.
