The Influence of Different Heat Treatment Methods on the Compressive Performance of AlSi10Mg Lattice Structure

本研究针对选择性激光融化制造的AlSi10Mg点阵结构,系统探讨了不同热处理方式对其微观结构及压缩性能的影响。通过准静态压缩实验评估了压缩性能,并深入研究了热处理方式与微观结构以及性能之间的相互关系。结果显示,不同热处理方式对AlSi10Mg的微观结构和压缩性能产生了显著影响,为后续选择性激光融化制造的AlSi10Mg合金的力学性能和微观结构研究提供了重要参考。特别值得注意的是,经过实验验证,最佳的热处理工艺为525℃-2 h-空冷 + 180℃-6 h-空冷。

This study focuses on the AlSi10Mg lattice structure manufactured by selective laser melting, and systematically explores the effects of different heat treatment methods on its microstructure and compression performance. The compression performance was evaluated through quasi-static compression experiments, and the relationship between heat treatment methods, microstructure, and performance was thoroughly studied. The results showed that different heat treatment methods had a significant impact on the microstructure and compressive properties of AlSi10Mg, providing important references for the mechanical properties and microstructure research of AlSi10Mg alloys manufactured by selective laser melting in the future. Of particular note, after experimental verification, the optimal heat treatment process is 525˚C-2 h-air cooling + 180˚C-6 h-air cooling.
