Inhaltszusammenfassung
The current paper is focussed on the nodular cast iron ASTM 80-55-06 (EN-GJS-600). The individual microstructure was investigated by light and scanning electron microscopy as well as micro-hardness measurements. Stress-controlled fatigue tests were performed at ambient temperature with testing frequencies of f = 5 Hz and f = 150 Hz. The cyclic deformation behaviour was characterised by means of mechanical stressstrain hysteresis (f = 5 Hz) as well as the change in temperature, electrical resi...The current paper is focussed on the nodular cast iron ASTM 80-55-06 (EN-GJS-600). The individual microstructure was investigated by light and scanning electron microscopy as well as micro-hardness measurements. Stress-controlled fatigue tests were performed at ambient temperature with testing frequencies of f = 5 Hz and f = 150 Hz. The cyclic deformation behaviour was characterised by means of mechanical stressstrain hysteresis (f = 5 Hz) as well as the change in temperature, electrical resistance and frequency (f = 150 Hz) measurements. Increasing testing frequencies result in higher values of the change in temperature caused by the increasing heat dissipation per second.» weiterlesen» einklappen
