Low cycle fatigue of austempered ductile cast iron alloyed with nickel at room and at depressed temperature

Original language description

Total strain controlled tests have been performed on cylindrical specimens of austempered ductile cast iron (ADI) with the aim to compare cyclic plasticity and the fatigue life at temperatures 23°C and ?45°C. The measurement of retained austenite by neutron diffraction before and after fatigue tests is used to discuss the cyclic stress-strain response. Cyclic hardening/softening curves, cyclic stress-strain curves and fatigue life curves were obtained for both temperatures. Cyclic stress-strain curve obtained at -45°C is shifted to higher stress amplitudes relative to room temperature curve. The fatigue life curves at both temperatures can be well approximated by the Manson-Coffin and Basquin laws.The Manson-Coffin curves are identical at both temperatures while the Basquin curve is shifted to longer fatigue life. Fatigue cracks initiated preferably from persistent slip markings at the interface of graphite nodule and the ausferrite matrix.
