CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishDamaging 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.
