Ductile iron, inozivikanwawo se ductile cast iron, nodular cast iron, spherical graphite iron, spherical graphite cast iron uye SG iron, imhando ye graphite-rich cast iron yakawanikwa muna 1943 naKeith Millis.Nepo mazhinji emhando dzesimbi yakakandwa isina kusimba mukunetsana uye brittle, ductile iron ine zvakawanda zvinokanganisa uye kuneta kuramba, nekuda kweiyo nodular graphite inclusions.Ductile iron haisi chinhu chimwe chete asi chikamu cheboka rezvigadzirwa zvinogona kugadzirwa nehuwandu hwezvinhu kuburikidza nekutonga kwe microstructure yavo.Izvo zvinowanzotsanangudza hunhu hweboka iri rezvinhu chimiro chegraphite.Mune ductile irons, graphite iri muchimiro chemanodule pane maflakes senge grey iron.Nepo akapinza graphite flakes achigadzira kushushikana kwenzvimbo mukati mesimbi matrix, akatenderedzwa nodule anotadzisa kugadzirwa kwepakatsemuka, nekudaro ichipa iyo yakakwidziridzwa ductility iyo inopa alloy zita rayo.
Austempered ductile iron (ADI; kureva, austenite tempered [7]) yakawanikwa muma1950s asi yakatengeswa uye yakabudirira makore akati gare gare.MuADI, iyo metallurgical chimiro inogadziriswa kuburikidza neyakaomesesa kupisa kupisa maitiro.
