In situ X-ray diffraction study on crystallization of shock-wave-quenched Zr-based bulk metallic glasses

Crystallization of Zr41.9Ti14.7Cu13.1Ni10.1Be20.2 (number indicate at.%) bulk metallic glasses prepared by shock-wave quenching and water-quenching are investigated by in situ X-ray diffraction under continuous heating conditions. Different phases and different precipitation sequences are found for both bulk metallic glasses. The differences in crystallization are probably attributed to different atomic configurations between the two bulk metallic glasses prepared by different ways.
