对 Pb 在 Fe 液中溶解度的实验数据进行评述,从而选出合理的数值,再通过简单的热力学处理,求出其与温度的依赖关系.将此关系与凝固点下降公式结合,算出 Fe-Pb 相图中偏晶点的成分和温度.对 Fe 在 Pb 液中溶解度的实验结果也作了适当的处理.在上述工作的基础上,给出了一个 Fe-Pb 相图.
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.
