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.

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.
