本文根据相图中紧邻相区及其边界关系的理论,提出了一个直接而简便的计算恒压相图中垂直截面图的方法。利用这个方法计算了Bi—Sn—Zn三元系恒压相图中若干不同类型、不同位置的垂直截面图。
In this paper, a direct and simple method of calculating the vertical cross-section of a constant pressure phase diagram is proposed according to the theory of the adjacent phase region and its boundary in the phase diagram. This method was used to calculate the vertical section of several different types and locations of the Bi-Sn-Zn ternary system constant voltage phase diagram.
