Thermal regimes of formation and parameters of the fine structure of amorphous alloys based on light rare-earth elements (E-La, Ce, Pr) with normal metals (M-Al, Cu, Ag) obtained by rapid cooling of melt layers on the inner surface of a rotating cylindrical heat receiver are studied. It has been shown that the alloys under study belong to materials with an average level of glass-forming ability (GFA), whichsolidify without crystallization in cross sections from 35 to 65 μm during quenching from a liquid state. Based on the correlation between the sizes of coherent scattering regions and the shortest interatomic distances found by X-ray diffraction for E-M amorphous alloys with the corresponding characteristics of metallic glasses of other classes, a conclusion was made about a close analogy of the atomic structure of noncrystalline phases fixed by quenching metallic melts. |
