| Abstract | In this study, gray cast iron ASTM A48 was subjected (1) to testing for effects of cooling rate on its impacts properties;and (2) to assessing the relationship between microstructure and properties. The cooling rate was varied by testing the fourcooling methods (1) As-cast; (2) Furnace-cooled; (3) Air-cooled; and 4) Green sand-cooled. It was found that the impactedproperties are governed by flat fractures that meet minimum energy density criteria. Thus, we established a correlation betweenthe microstructure and impact properties of GI ASTM A48 for conformance analysis to develop a predictive relationship. Theseinclude test specimen size and energy consumption patterns. As a result, the impact properties of GI ASTM A48 are finallypredictable. This results in good efficiency and can be applied to heat treatments of some new materials. |
