Abstract
Damaging micromechanisms in a ferritic ductile cast iron were investigated by using a scanning electron microscope with a microtensile holder. Strain rate influence was investigated: tensile tests were performed according to a step by step experimental procedure and specimens surfaces were observed by means of a scanning electron microscope (SEM) during the test ("in situ" tests). Experimental results do not confirm matrix-graphite nodules debonding as the main damaging micromechanisms involved in ferritic ductile irons failure. (c) 2010 Elsevier Ltd.
