Original abstract

INCONEL 713 LC is popular material for more exposed parts of turbine engines. These parts are usually exposured to high dynamic stress (fatigue processes, creep) and variable temperatures in corrosion environment (hot corrosion, oxidation and erosion). The most frequent failure of these parts is fatigue damage, which is started from inclusions at the surface. Topography of the surface of IN 713 LC in as received state and after low cycle fatigue tests at room temperature 23C and 800C was studied. Surface relief was formed by slip bands (intrusions and extrusions), which are generated by mechanism of microplastic deformation. Surface topography was measured by means of laser scanning confocal microscope LEXT OLS3000 (Olympus). Achieved results were compared with AFM Autoprobe (VEECO) and SEM (Philips XL30) measurements.

Inconel 713LC je velmi oblíbený materiál pro exponované součásti. Mezi degradační procesy vysokoteplotních součástí patří únavové procesy, creep, vysokoteplotní koroze, oxidace a eroze. Nejčastějšími příčinami poškození je právě únava, která se šíří inkluzemi z povrchu součásti. Topografie povrchu byla studována na výchozích vzorcích bez expozice a dále po nízkocyklovém únavovém testu za teplot 23C a 800C. Povrch byl studován metodami rastrovací konfokální mikroskopie, rastrovací elektronové mikroskopie a AFM.
