Abstract

Thermodynamic data between tramp elements(copper and tin) and alloying elements in molten iron are necessary to know the influence of them on the property of steel. However, the available data are not enough because of the difficulty of the measurements. One of the purpose of this study is to develop a method to measure the thermodynamic data of tramp elements. In this work, we have tried to measure the oxidation equilibria of copper in molten iron by using silver as an intermediate phase. By applying this method, the interaction between copper and alloying elements in iron has been investigated. Moreover, the interaction between tin and alloying elements in iron has also been investigated by using immiscibility between Fe and Ag phases.
