摘要
利用余瑞璜的经验电子理论及吕振家-王绍铿的结合能公式,分析了金属间化合物Co_3Ti和CoTi的晶格常数和结合能,晶格常数的计算结果与实验值相当符合,并对金属的脆性与金属中晶格电子和共价电子数量的关系进行了讨论。
By using Yu's[1,2] 'empirical electronic theory in solid and molecules', the cal-culated lattice constants of intermetallic compounds Co3Ti and CoTi are obtained, which agree well with to the experimental data. The cohesive energies of these two alloys are calculated with the pairwise potential function given by Lu[3] and Xu[4], and the results are reasonable. The relationship between the brittleness of these alloys and the concept of 'lattice electron' in metals is discussed at the last section.
