Quantitative Evaluation of Carbon-Enriched Stabilised Austenite in Cast Austempered Ductile Iron of Varying Section Thickness

The quantity of carbon-enriched stabilised austenite (γHC) in austempered ductile iron (ADI) with various casting  thicknesses was evaluated in this study. Ductile iron grade that conforms to ASTM A536 65-45-12 was cast,  specimens of section thickness in the range of 5 to 25 mm were machined, isothermally treated to 820°C austenitising  temperatur...
