Three partial structure factors Sij(Q) have been evaluated from the scattered X-ray intensities of liquid Na -K and Al - Mg alloys assuming that the Sij(Q) are independent of the relative abundance of the respective elements in the alloys. The functions Sii(Q) and Sjj(Q) and the reduced radial distribution functions Gii(r) and Gjj(r) obtained in this work are very similar to those observed in the respective pure liquid metals. In both cases, Sij(Q) and Gij(r) have maxima which lie in between those of the pure elements. From these results, liquid Na -K and Al -Mg alloys are interpreted as random mixing fluids. A comparison between the partial structure factors obtained in this work and those calculated from the hard sphere model was made. Adequate agreement was obtained on the low angle side of the first peak, but agreement on the whole pattern is not necessarily found. The electrical resistivity was calculated using Faber-Ziman’s theory and compared with experimental data.

A variety of materials containing many different microstructures have been examined with the USS MVEM. Three topics have been selected to illustrate some of the more recent studies of diffraction phenomena and defect, grain and multi-phase structures of metals and minerals.(1) Critical Voltage Effects in Metals and Alloys - This many-beam dynamical diffraction phenomenon, in which some Bragg resonances vanish at certain accelerating voltages, Vc, depends sensitively on the spacing of diffracting planes, Debye temperature θD and structure factors. Vc values can be measured to ± 0.5% in the HVEM ana used to obtain improved extinction distances and θD values appropriate to electron diffraction, as well as to probe local bonding effects and composition variations in alloys.
