Effect of Graphite Degradation on Thermal Analysis Cooling Curve of Ductile Iron Melt

Article Preview

Abstract:

In this work, characteristic temperatures of thermal analysis cooling curves of ductile iron melt during fading process were compared, and the graphite morphology of the corresponding samples were studied. Results show that the cooling curves response degradated nodularization promptly, and there are correspondences between the characteristic temperatures of cooling curve and graphite morphology. It indicates that it is feasible to estimate the fading situation of the melt rapidly by identifying the characteristic temperatures of the thermal analysis cooling curves.
