Nízkocyklová únava tvárné litiny s 2,8 % niklu
Tesařová, H. ; Petrenec, Martin ; Pacal, B. ; Musilová, I.
Cast ductile iron with the ferritic matrix alloying with 2.8% Ni was subjected to cycling with constant strain amplitudes and the cyclic stress-strain response and fatigue life were studied experimentally. The original microstructure is documented using light microscope. Fracture surface was studied using scanning electron microscopy. Manson-Coffin and Basquin laws can reasonably approximate the fatigue life data. Fatigue crack initiation from shrinkage cavity is documented.
Low cycle fatigue of ferritic ductile cast iron with alloying nickel
Tesařová, H. ; Petrenec, Martin ; Pacal, B.
Total strain controlled tests have been performed on cylindrical specimens of ductile cast iron with aim to assess of the fatigue resistance. Cyclic hardening, cyclic stress-strain and fatigue life curves were obtained. The microstructure is documented using light microscope. Fracture surface was studied using scanning electron microscopy. Manson-Coffin and Basquin laws can reasonably approximate the fatigue life data. Fatigue crack initiation close to the surface is documented.
