The structural results for molten Ni 81 B 19 are compared with the structure of a metallic glass which can be obtained at the same composition by rapid quenching the melt within a melt spin equipment. Structural relationship exists between the molten and the amorphous state. This feature follows especially from a marked asymmetry of the second maximum of the structure factor obtained from the melts, to which corresponds the splitting up of the second maximum in the total structure factor of the amorphous specimen. With the Ni 53 B 47 -and the Ni 4 3B 57 -melts which don't belong to the concentration range of glass-forming Ni-B-melts no peculiarities in the range of the second maximum of the structure factor were observed.

The total structure factors as well as the total pair correlation functions for amorphous Mg85.5Cu14.5 (by neutron and X-ray diffraction) and for amorphous Mg70Zn30 (by X-ray diffraction) were determined. Both alloys show similar chemical short range order effects. From the total pair correlation function of the Mg85.5Cu14.5 glass, partial coordination numbers and atomic distances could be extracted. Comparison with the structure of crystalline Mg2Cu suggests that the short range order around the copper atoms is similar in the amorphous and the crystalline phase. The densities of both amorphous alloys were measured yielding negative excess volumina.

The total structure factors as well as the total pair correlation functions of amorphous Mg 84 Ni 16 and Mg3 0 Ca 70 were determined by X-ray diffraction. The Mg-Ni glass shows rather strong chemical short range ordering. By Gaussian fit of the total pair correlation function partial coordination numbers and atomic distances were obtained. Similar surrounding of the Ni atoms in the amorphous phase and in crystalline Mg 2 Ni was found. The structural features of the Mg-Ca glass differ from those of the Mg-Ni glass.
