Determination of Microamount of Carbon in Selected Samples of Iron, Steels, Ferro-Alloys and Metal Powder

Abstract

The influence of non-meta1lic components such as nitrogen, hydrogen and carbon has significant effect on the microstructure and ultimately on the mechanical properties of iron steels and ferro-alloy products. For the quantitative estimation of carbon content, some selected samples of iron, low alloy steel, high alloy steel, stainless steel, ferro-alloys, metal powders and the standards of these materials have been analyzed for the measurement of carbon content in microamount by using high frequency (HF) energy combustion and infrared (IR) detection technique. The accuracy of the method was evaluated statistically and the result data were compared with the literature values.
