Abstract

Several physical and mechanical properties have been determined for two amorphous alloys which are based on the same U-14.3at.% Fe composition. One alloy has been produced by liquid quenching and the other has been produced by neutron irradiation. Compared with the liquid-quenched glass, the irradiation-produced amorphous alloy has (a) a lower density, (b) a smaller resistivity, (c) a higher superconducting transition temperature and (d) a lower hardness. The properties are correlated with previously obtained X-ray diffraction and calorimetry data and are interpreted in terms of structural relaxation phenomena associated with a decreased degree of short-range order in the irradiation-produced amorphous alloy. Significant differences exist in the superconducting transition temperatures measured by resistive and inductive techniques, also reflecting structural differences between the alloys. The results are also correlated with the properties of the compound U6Fe, which is the crystalline counterpart of these amorphous alloys. © 1981.
