摘要

工程材料的研究一直集中在开发能够有效承受载荷和吸收能量的轻质结构上。本研究涉及通过融合选择性激光熔化技术和渗铸技术来创造一种新型铝基复合材料。复合材料的力学性能是通过改变增强体细胞的参数来控制的。结果表明，蜂窝结构与基体之间形成了较强的冶金结合，大大提高了复合材料的综合性能。六方管状金属间化合物（IMC）层和蜂窝填充管增强了蜂窝填充管/Al基复合材料（HFT/AMC）。复合材料的抗压强度与IMC层含量呈正相关。对不同结构参数的蜂窝状填充管制成的高频高频/超导材料的数据分析证实了这种关系。蜂窝状填充管增强材料的引入和IMCs的分布规律为Al基复合材料的设计和开发提供了新的方法和思路。

Mechanical properties of novel 3D printing 316L stainless steel honeycomb structure reinforced aluminum matrix composites

The investigation of engineering materials has consistently focused on developing lightweight structures that can bear loads and absorb energy efficiently. This study involved the creation of a novel aluminum (Al) matrix composite by merging selective laser melting technology with infiltration casting. The mechanical properties of the composite material were manipulated by altering the parameters of the reinforced body cells. The results show that a strong metallurgical bond is formed between the honeycomb structure and the matrix, which greatly improves the overall performance of the composite. The hexagonal tubular intermetallic compounds (IMC) layer and the honeycomb-filled tube strengthen the honeycomb-filled tube/Al matrix composites (HFT/AMC). The new composite material's compressive strength was found to be positively related to the percentage of the IMC layer. The analysis of data from HFT/AMCs made from honeycomb-filled tubes with structurally different parameters demonstrated this relationship. The introduction of honeycomb-filled tube reinforcements and the distribution regulation of IMCs provide new methods and ideas for the design and development of Al matrix composites.
