Description
The influence of sulfur content on the matrix structure of cast iron was studied using spheroidal graphite and flake graphite cast iron samples whose chemical composition was 3.6mass%C and 2.0mass%Si. The sulfur content of the flake graphite cast iron samples was changed from 0.006mass% to 0.076mass% with FeS addition. The matrix structure was observed for the as cast and heat treated samples. The heat treatments were annealing (furnace cooled) and normalizing (air cooled), cooled from the different heating temperature, as 850°C, 950°C and 1050°C. <br> The formation of pearlite structure was accelerated with sulfur in flake graphite cast iron samples. The formation of pearlite in spheroidal graphite cast iron was nearly identical with that of the low sulfur flake samples. When the heating temperature was 850°C, the pearlite morphology was granular and the pearlite formed from the higher temperature and the as cast sample, the morphology was lamellar. The difference should be affected by the solubility of carbon in austenite.
