摘要
溶质原子团簇是指合金中几个到几十个溶质原子的无序聚集。作为时效析出序列的重要一环,溶质原子团簇不仅可以通过调控铝合金时效析出行为而改善显微组织,而且可以有效地改善合金的力学性能。对铝合金中溶质原子团簇的表征方法、强韧化调控机制及其在铝合金中的典型应用等几个方面进行了综述,对溶质原子团簇未来的研究方向进行了展望。
Solute atomic clusters are disordered agglomeration of a few to dozens of solute atoms in an alloy.As an important part of aging precipitation sequence,solute atomic clusters can not only regulate aging precipitation behavior of aluminum alloys to improve the microstructure,but also effectively improve the mechanical properties of the alloy.The characterization methods of solute atomic clusters in aluminum alloys,the regulation mechanism of strengthening and toughening,and their typical applications in aluminum alloys are reviewed.The future research direction of solute atomic clusters is prospected.
