Structural Studies of New Metallic Amorphous Alloys with Wide Supercooled Liquid Region (Overview)

摘要

A review is given of recent structural studies in new metallic amorphous alloys with an extremely large glass-formability, such as La_(55)Al_(25)Ni_(20), Zr_(60)Al_(15)Ni_(25), Zr_(70)Ga_(10)Ni_(20) and Zr(33)Y_(27)Al_(15)Ni_(25) amorphous alloys. The origin of the good thermal stability in these amorphous alloys are discussed from the viewpoint of the local atomic structure in amorphous and crystallized states.
