Abstract
A reversible phase transition between amorphous and crystalline in bulk met allic glass (BMG) Zr41.2Ti13.8Cu12.5Ni10Be22.5 has been investigated under high pressure at room temperature. The BMG displayed a structure memory und er high pressure as detected by in situ synchrotron radiation of x-ray diff raction and resistance measurement in a diamond anvil cell. Direct experime ntal observations found that the crystallization of the BMG occurred at 24 GPa on uploading and the crystalline phase reverted back to the amorphous s tate during downloading. This unusual phenomenon was discussed thermodynami cally. (C) 2000 American Institute of Physics. [S0003-6951(00)04220-0].
