Abstract
The metallic glass Pd58.8Si20.6U20.6 has been produced by melt-spinning and was annealed in a helium stream at 790–805 K for 120–200 s.
During this procedure the material transforms into the so-called quasi-crystalline state. Differential scanning calorimetry (DSC) measurements have shown that more than 92% of the former metallic glass becomes quasi-crystalline, less than 1% is crystallized and the rest remains amorphous.
The data for elastic neutron and X-ray scattering are presented. The computed total structure factors are compared. In contrast to the X-ray results, the neutron measurements show no peaks below a scattering vector of 2 Å−1, which seems to indicate some chemical short-range order.
