Castings were obtained using modification and filtration methods. Additionally, casting made of MAR-247 were subjected to heat treatment consisting of solution treatment and subsequent aging. During low-cycle fatigue test the cyclic creep process were observed. It was demonstrated that the fine-grained samples have significantly higher durability in test conditions and , at the same time, lower values of plastic deformation to rupture Δϵpl. It has been also proven that durability of fine-grained MAR-247 samples can be further raised by about 60% using aforementioned heat treatment.}, type={Artykuły / Articles}, title={Durability of MAR-247 and IN-713C Nickel Superalloys under Cyclic Creep Conditions}, URL={http://journals.pan.pl/Content/88782/PDF/03_paper.pdf}, doi={10.1515/afe-2015-0071}, keywords={Nickel superalloys, Macrostructure modification, Heat treatment, Low-cycle fatigue, Cyclic creep}, }
