抄録

The vapor pressure of phosphorus in molten carbon-saturated iron with phosphorus content of 0.20–0.92 mass% at 1 473–1 673 K was measured by double Knudsen cell mass spectrometry. In the molten carbon-saturated iron, phosphorus behaved according to Henry's law in the composition range. The activity coefficient of phosphorus in this conditions relative to infinite dilute solution, f_P, and the interaction parameter of carbon on phosphorus in molten iron, e′_P^C, were determined to be as follows:<br>log f_P = −300/T+0.82(±0.05), e′_P^C = 120/T+0.061(±0.010)
