Abstract

传统上,晶格畸变被认为是高熵合金区别于普通合金的结构特征。然而如何理解和表征在高熵合金中的晶格畸变还是一个悬而未决的问题。本文以最近发表的理论工作(包括理论模型和第一性原理计算)和实验工作为基础,主要探讨在高熵合金(乃至成分复杂合金)中晶格畸变(以及伴生的内禀残余应力或应变场)的物理来源以及实验特征。
Lattice distortion has been deemed as one of the most distinctive structural features of high-entropy alloys. However, despite its fundamental importance, the notion of lattice distortion and its characterization is still an issue under debate. In this work, based on the recent work on theoretical modeling, atomistic simulations and experiments, the physical origin of lattice distortion in high-entropy alloys and its resultant intrinsic residual stresses or strains are discussed.
