摘要
在考虑理论计算合金形成热的各种影响因素的基础上 ,用Miedema二元合金生成热模型计算了彩色热镀锌用Zn Mn和Zn Ti二元溶液的混合焓ΔHmix与添加元素的摩尔分数之间的关系 ;利用Tanaka近似关系式及一些基本热力学关系计算了上述两个二元体系的过剩混合熵ΔSEmix、过剩混合自由能ΔGEmix及各组元的活度。结果表明 ,Zn Mn和Zn Ti两溶液相对于理想溶液都有很大的负偏差。
Considering different factors that affect the formation heat of binary alloys, the relationship among Zn Mn and Zn Ti formation heats and mole fraction of additives were obtained by Miedema's mode; Δ S E mix , Δ G E mix and activities of the two systems were calculated by Tanaka model and some relationships of thermodynamics. The results indicate that Zn Mn and Zn Ti solutions have a rather large negative deviation relative to ideal solution. [
