Phase transitions of Zr sub(41.2)Ti sub(13.8)Cu sub(12.5) Ni sub(10)Be sub(22.5) bulk metallic glass at pressures up to 27 GPa

Phase transitions of Zr sub(41.2)Ti sub(13.8)Cu sub(12.5) Ni sub(10)Be sub(22.5) bulk metallic glass at pressures up to 27 GPa

The phase transitions of Zr sub(41.2)Ti sub(13.8)Cu sub(12.5)Ni sub(10) Be sub(22.5) bulk metallic glass have been investigated under high pressures and at room temperature. Direct resistance measurements in a diamond anvil cell provide evidence of a reversible transition between amorphous and cryst...

Zusammenfassung:The phase transitions of Zr sub(41.2)Ti sub(13.8)Cu sub(12.5)Ni sub(10) Be sub(22.5) bulk metallic glass have been investigated under high pressures and at room temperature. Direct resistance measurements in a diamond anvil cell provide evidence of a reversible transition between amorphous and crystalline phases; crystallization events occurred at 24 and 26.2 GPa on uploading, and crystalline-to-amorphous phase transitions were observed at 16 and 10.6 GPa on downloading. The phase transitions were confirmed by transmission electron microscopy observations.
