In the combusion method of carbon analysis of cast iron, the sample is usually obtained by turning or drilling. In these cases, the size of the chips affects a great influence on the analytical value, because graphite particles in cast iron separate from chips and consequently small analytical value is often obtained. This tendency is the greater in the smaller size of chips, and also the greatest in the case of spheroidal graphite cast iron, next in malleable iron, and the least in flaky graphite cast iron. For obtaining, therefore, the most reliable value in the carbon analysis of cast iron, all chips turned or drilled must be used for each analysis. The change of carbon content in spheroidal graphite cast iron with the time after the addition of Mg into its melt is studied and discussed.
