Abstract
Ghisa nodulare e procedimento per ottenere ghisa nodulare detta ghisa nodulare comprendendo: una matrice metallica bainitica, martensitica, perlitica o ferritica avente un grado di purezza di circa il 99,6% in cui i contenuti zolfo e fosforo sono mantenuti inferiori a 0,015% e 0,04% rispettivamente; da 10 a 12% in volume di particelle di grafite e da circa 0,2 a 1,2% in volume di particelle di carburo di elevata durezza del tipo Mc, dette particelle essendo disperse nella matrice metallica fusa, in cui M è almeno uno degli elementi scelti dal gruppo costituito da Ti, Ta. Zr, Hf, V e Nb.L'invenzione riguarda pure un procedimento per ottenere ghisa nodulare comprendente le fasi di: aggiungere ad un bagno di ghisa grigia contenente meno dello 0,015% di zolfo e meno dello 0,04% di fosforo, un carico tra circa 0,2 e 1,2% riferito al peso del bagno di almeno una ferrolega avente la formula Fe-FeM o Fe-MC, in cui M è almeno uno degli elementi scelto dal gruppo costituito da Ti, Ta, Zr, Hf, V e Nb; effettuare almeno una nodulizzazione del bagno mediante inoculazione di magnesio a basso tenore di ferrosilicio in esso; e scaricare il bagno metallico nodulizzato nello stampo.(Fig. 2)
