Original abstract
Cast polycrystalline nickel base superalloy Inconel 713LC is used for critical parts of gas turbine engines that are subjected to repeated elastic-plastic loading in aggressive environments at variable temperatures. Thermal barrier coatings (TBC) can prolong the component life particularly by a reduction of temperature gradient during heating and cooling. In the present work, the high temperature low cycle fatigue behaviour of cast nickel-based superalloy Inconel 713LC in as-received condition and with TBC was studied. The microstructure of the material is characterized by dendritic grains with carbides and shrinkage pores. The average grain size was 0.66 mm.
