本研究探讨了决定非晶合金性能的结构因素。非晶合金的性质与原子堆积密度密切相关，其特征在于短程有序（SRO）原子团簇和自由体积。随着堆积密度的增加，弹性模量和强度增加，塑性降低。我们讨论的基本微观结构方面，影响几个代表性的性质的非晶合金的包装状态，其特征在于分数的SRO原子团簇。(C)2007 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
This study examined the structural factors that determine the properties of amorphous alloys. The properties of amorphous alloys were found to be intimately related to the atomic packing density, characterized by short-range ordered (SRO) atomic clusters and free volume. With increasing packing density, the modulus and strength increased, while the plasticity decreased. We discuss the fundamental microstructural aspects that influence several representative properties of amorphous alloys in terms of the packing state characterized by fractions of SRO atomic clusters.
