摘要
In-situ SR-XRD measurements revealed that the crystallization process in Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass is significantly different from that in tradi-tional glasses. Subsequent heating at 10 GPa converts the sample from amorphous phase into the metastable fcc phase and then leads to the fcc phase back to the amorphous phase, indicating that there exists ’reversible’ phase transition phe-nomena in the material under high pressure and high tem-perature.
