On Decomposition of Amorphous Phase in Metallic Classes

摘要

Structure evolution in metallic glasses under heating and deformation is studied and discussed. Special attention is devoted to the pre-crystallization processes occurring at heating and deformation. A separation of uniform amorphous phase and formation of regions with different type of short range order and/or different composition in light amorphous Al-Ni -RE (RE = La, Gd or Y) alloys is described. Possible reasons of amorphous phase decomposition are considered.
