| Abstract |
In the spheroidal graphite cast iron, the effects of carbon-content and cooling velocity on the matrix structure were examined quantitatively by differentiating the carbon content and the diameter of sample at constant silicon content. The important results of this study are as follows; 1. With 0.1% increase of carbon content, the amount of the pearlite matrix showed 4.5% decrease in hypoeutectic and 1.7% decrease in hypereutectic. 2. With 0.1% increase of carbon content, the amount of the ferrite showed 3.8% and 1.1% increase in Hypoeutectic and Hypereutectic respectively. 3. The effects of carbon content are larger than that of cooling velocity on the matrix structure. |
