Abstract
Energy-dispersive X-ray diffraction and white-beam radiography have been conducted on a sample of Materion Vit 106a bulk metallic glass, Zr58.5Cu15.6Ni12.8Al10.3Nb2.8 (at %) under high pressure and high temperature conditions. The sample was compressed at room temperature to 5.03 GPa using a Paris-Edinburgh (PE) Press at Beamline 16-BM-B, HPCAT of the Advanced Photon Source and then was heated to 800 °C . The measured structure factor, S(q) to a large q = 19 Å-1, was used to determine information about the internuclear bond distances between various species of atoms within the bulk metallic glass sample. The sample pressure was determined with MgO as the pressure standard. The first sharp diffraction peak (FSDP) of the S(q) function shifts from 2.58 Å-1 at ambient conditions to 2.63 Å-1 at 5.03 GPa.
