摘要：

A high-resolution transmission-electron-microscopy study of the relaxation and crystallization of a Ni80B20 amorphous alloy has been performed. An intermediate state, corresponding to the crystallization of Ni3B and to the formation of amorphous nickel, is discussed. This noncrystalline nickel is shown to consist of regions with only short-range order, together with regions of nascent crystallinity with a high density of defects, which resemble grain-boundary structures.
