| description | In the last decades, damaging micromechanisms in ductile cast irons (DCIs) have been widely
investigated, considering both the matrix microstructure and the loading conditions influence. Considering the
graphite nodules, they were initially considered as voids embedded and growing in a ductile metal matrix
(especially considering ferritic ductile cast irons). Recent experimental results allowed to identify a more
complex role played by the graphite nodules, depending on the matrix microstructure.
In this work, damaging micromechanisms in a pearlitic DCI were investigated by means of tensile tests
performed on notched specimen, mainly focusing the role played by graphite elements and considering the
stress triaxiality influence. |
