Phase transition of shock-loaded ZrTiCuNiBe bulk metallic glass under continuous heating

Abstract

Phase transition of Zr41.9Ti14.7Cu 13.1Ni10.1Be20.2 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. © 2008 The Japan Institute of Metals.
