Abstract
The effect of austenitizing temperature and time on the processing window of 3.60wt%C - 2.50wt%Si - 0.80wt%Cu ductile cast iron and that of the amount of copper added were investigated. The second stage reaction at 400oC was retarded with increased austenitizing temperature. The widest processing window was obtained at the lower austempering temperature with the increased time at the same austenitizing temperature. The width of the widest processing window was decreased with the increase of time at the same austenitizing temperature. The width of processing window was increased with the increased amount of copper added.
