LOW CYCLE FATIGUE BEHAVIOUR OF NICKEL BASE SUPERALLOYS IN713 LC AND MAR-M-247 HIP AT ELEVATED TEMPERATURE
Original language description
Despite the fact that first generation nickel base superalloy IN 713 LC (low carbon) is used more than 50 years it is still desired alloy in the aircraft gas turbine market because of its outstanding high temperature properties and also low price. Hot isostatically pressed alloy MAR-M-247 HIP is one of the second generation nickel base superalloys that can replace the IN713 LC and become a leading alloy for gas turbine aircraft engines. In the present work, isothermal low cycle fatigue (LCF) of polycrystalline nickel base superalloy IN713LC LG (low grain) and MAR-M-247 HIP was studied. Microstructure and fracture surface of both alloys were studied using optical (OP) and scanning electron microscopy (SEM). The microstructure of the materials is characterized by dendritic grains, carbides and casting defects. Size and morphology of precipitates was evaluated. Fractographic observation has been made with the aim to reveal the fatigue crack initiation place, its kind and relation to the c
