Abstract To elucidate the relation between optimum solubility and temperature,the critical assessment of the experimental data of solubility of Pb in liquid Fe,or of Fe in liquid Pb,have been made.By combining these relations with the liquids curve calculated from Clausius-Clapeyron equation,the composition and temperature of the monotectic point on the Fe-Pb phase diagram have been esti- mated.Thus,an Fe-Pb phase diagram may be drawn on the basis of above men- tioned studies.
