amorphous-to-amorphous configuration change in Ca-Al metallic glasses

MG. The transfer of s electrons into d orbitals under pressure, reported for the pressure-inducedphase transformations in pure polycrystalline Ca, is suggested to explain the observation of anamorphous-to-amorphousconfigurationchangeinthisCa-AlMGsystem.Resultspresentedhereshowthatthepressureinducedamorphous-to-amorphousconfigurationisnotlimitedtofelectron-containingMGs.
