Abstract
Modificatorul conform inventiei, în scopul obtinerii unui grafit bvermicular stabil, chiar si la continuturi mai mari de sulf în fonta, în conditiile unor piese cu pereti grosi sau cînd perioada de mentinere de la mofidificare la turnare este mai mare de zece minute, contine maximum respectiv 10% Mg, 6% Ti, si 15% cu, minimum 20% Si, 8-20% Al, 0,2-10% ca si 0,2-10% Mn, mentinîndu-se raporturile între continuturile de Al si Ti cuprinse între 2 si 20 si raportul de control între suma continuturilor de Mg si 0,3 din continut procentual de Ca, între 0,8 si 4,0.
