It is shown that the x-ray powder diffraction patterns of rapidly quenched MnAl(6) and Mg(32)(Al,Zn)(49) and the neutron powder diffraction pattern of MnAl(6) are compatible with the proposed 820-atom primitive cubic structure [Pauling, L. (1987) Phys. Rev. Lett. 58, 365-368]. The values found for the edge of the unit cube are 23.365 A (x-ray) and 23.416 A (neutron) for MnAl(6) and 24.313 A (x-ray) for Mg(32)(Al,Zn)(49).
研究表明,快速淬火 MnAl(6)、Mg(32)(Al,Zn)(49)的 X 射线粉末衍射图谱和 MnAl(6)的中子粉末衍射图谱与所提出的 820 个原子的原始立方结构一致[Pauling, L. (1987) Phys. Rev. Lett. 58, 365-368]。对于 MnAl(6),单位晶胞边缘的测量值分别为 X 射线 23.365 A 和中子 23.416 A,Mg(32)(Al,Zn)(49)为 X 射线 24.313 A。
