本文介绍了亚稳态Fe50Cu50固溶体晶格常数的测量结果,应用金属结构的经典概念并考虑到原子核周围电子密度的高斯型球对称分布,导出了计算金属中一个原子的平均内能和两种不同金属原子相互作用势的普遍公式。对亚稳态Fe50Cu50合金原子相互作用势作计算,得到平衡时fcc-FeCu的晶格常数为0 36433nm与实验测量结果接近,也与H R Gong等人对亚稳态FeCu合金的研究结论一致,证实了亚稳态Fe50Cu50合金是以fcc结构形式存在的固溶体。

This paper has introduced the measure result of lattice constant of the metastable Fe_(50)Cu_(50) solid solutions. The universal formulases of a average internal energy of atom in metal and the two different kinds of metal atomic interaction potential have been derived by applying to the classical concept of the metalic structure and concerning the Gauss type ball symmetry of the around electronic density of atomic nucleus. It has been calculated that The atom interaction potential of the metastable FeCu alloys, When getting balance, the lattice constant of fcc-FeCu is 0.36433 nm and is close to with experiment measure result, and with the research conclusion of H.R. Gong etc. for the FeCu alloy of metastable state. It is verified that the metastable Fe_(50)Cu_(50) alloys is made of fcc structure solid solutions form.
