摘　　要：高熵合金是一种由多种元素组成的多主元合金,在非理想状态下元素分布不均匀,且对合金中的位错滑移行为有重要影响。这种不均匀性可通过改变合金各组元的原子比例或添加其他元素来控制而对其性能产生影响。因此,深入研究合金凝固过程相结构变化以及位错运动规律具有重要的理论意义。本文将从合金凝固生成的位错行为、微观组织、相形成与力学性能的关系等进行研究,综述元素分布对高熵合金影响研究现状,并对合金的未来进行展望。High entropy alloys are multi-principal alloys consisting of a variety of elements,and in a non-ideal state the distribution of elements is inhomogeneous and has a significant effect on the dislocation slip behaviour in the alloy.This inhomogeneity can be controlled by changing the atomic ratio of each element of the alloy or by adding other elements to affect its properties.Therefore,it is of great theoretical importance to investigate the changes in phase structure and dislocation movement during the solidification of alloys.This paper will examine the dislocation behaviour,microstructure,phase formation and mechanical properties of solidification-generated alloys,review the current status of research on the influence of elemental distribution on high-entropy alloys,and provide an outlook on the future of alloys.
