| 摘 要： | 铝和过渡族元素在镍的面心立方晶格中的极限共同溶解度,取决于组元的平均原子量与其化合价电子浓度之间的线性关系。这一规律建立在平衡合金化规则的基础上,借助此规则,通过对失衡度及其符号的不太复杂的计算,便可预测有害于合金的化合物的形成及元素的偏析。采用平衡合金化规则评定相的稳定性,比现行相计算法有许多优点。平衡合金化规则不仅可广泛用于实际冶金学,而且可用于新合金化系统相的状态的研究。

| Abstract: | The ultimate common solubility of aluminium and transitional elements in FCC lattce of nickel is depended upon the linear relationship between average atomic mass and concentration valence electrons of components. This rule is established on the law of equilibrated alloying, with its help and through simple calculation of degree and symbol of de-equilibriam the formation of detrimental compounds and elements segregation may be predicted in advance. Evaluating stability in this way gives a series of advantages by-comparison with phacomp and other variations. Regulation of equilibrated alloying may have wide use not only in applied metallurgical research, but also in phase condition study of new alloying systems. |
