Newton Thermal Analysis of Gray and Nodular Eutectic Cast Iron

Abstract

The purpose of this work is to analyze the capability of Newton Thermal Analysis (NTA) to detect differences of the solidification kinetics between eutectic gray and ductile irons obtained from the same base alloy. The NTA experimental output has been analyzed with a simple micromacro modeling approach. The outcome of this work suggests that NTA has a good potential as a qualitative tool to characterize the solidification kinetics of alloys.
