Determination of microamount of carbon in selected samples of iron, steels, ferro-alloys and metal powder

The influence of non-metallic components such as nitrogen, hydrogen and car bon has significant effect on the microstructure and ultimately on the mech anical properties of iron steels and ferro-alloy products. For the quantita tive estimation of carbon content some selected samples of iron, low riley steel high riley steel stainless steel ferro-alloys metal powders and the s tandards of these materials have been analyzed for the measurement of carbo n content in microamount by using high frequency (HF) energy combustion and infrared (IR) detection technique. The accuracy of the method was evaluate d statistically and the result data were compared with the literature value s.
