Abstract

The effect of pressure on the crystallization behavior of metallic glass Fe72P11C6Al5B4Ga2 alloy with a wide supercooled liquid region has been investigated by in situ high-pressure and high-temperature x-ray diffraction measurements using synchrotron radiation. In the pressure range from 0 to 2.4 GPa, the crystallization temperature, Tx, increases with pressure, p, having a slope of 30 K/GPa while a minimum in Tx was detected in the range from 2.4 to 3.9 GPa. With a further increase of p, Tx is independent of p. The Tx vs p behavior can be qualitatively explained by the suppression of atomic mobility and changes of the Gibbs free energy of various phases with pressure. ©2000 American Institute of Physics.
