Abstract

Phase transition of Zr_41.9Ti_14.7Cu_13.1Ni_10.1Be_20.2 bulk metallic glasses (BMGs) treated by shock loading (transition from a solid state to a solid state) and prepared by shock-wave quenching (transition from a solid state to a liquid state to a solid state) are investigated by in situ X-ray diffraction measurements under continuous heating conditions. The thermal properties, precipitation phases and phase transitions of the shock-loaded and shock-wave-quenched BMGs are found to be different from those of water-quenched BMGs. The differences are probably due to different structures between the BMGs induced by complex effects of shock loading.
