本文用FLAPW-Fourier方法测定了Al-Cu-TM-Si(TM = Fe和Ru)1/1 - 1/1 - 1/1近似式和几种B2化合物(CuZn,NiZn,NiAl,MnZn和AlMg)的e/a值。发现以过渡金属元素为伴元素的NiAl、NiZn和MnZnB_2-化合物不再被认为是3/2电子化合物。此外,我们发现,e/a值不是唯一分配给一个给定的过渡金属元素,而是取决于其周围的环境。因此,很难将其用作合金设计中的通用参数。
Abstract By using the FLAPW-Fourier method, we could determine the e/a value for Al–Cu–TM–Si (TM = Fe and Ru) 1/1 – 1/1 – 1/1 approximants and several B2 compounds including CuZn, NiZn, NiAl, MnZn, and AlMg. The NiAl, NiZn and MnZn B2-compounds involving the transition metal element as a partner element are found to be no longer regarded as the 3/2 electron compounds. Moreover, we found that the e/a value is not uniquely assigned to a given transition metal element but depends on its surrounding environments. Hence, it is difficult to use it as a universal parameter in an alloy design.
