摘要	电子束自由成形制造（EBF3）因其适用于太空环境而受到研究人员的广泛关注。本文研究了通过EBF3制造的TiB2/Al-Zn-Mg-Cu复合材料的微观结构和力学性能。结果发现，该复合材料的主要相为α-Al基体和均匀分布的TiB2颗粒。组织中存在等轴晶粒，平均晶粒尺寸分布范围为17.3μm至22.2μm。从基体到零件顶部，横截面显微硬度总体呈增加趋势，从66HV增加到128HV。该增材构件在水平方向上的极限抗拉强度为360MPa，屈服强度为216MPa，伸长率为16%。
Abstract	Electron beam freeform fabrication (EBF3) is attracting more and more attention from researchers due to its suitability for space environments. In this paper, we report the microstructure and mechanical properties of a TiB2/Al-Zn-Mg-Cu composite manufactured by EBF3. The main phases were α-Al and TiB2 particles. There were equiaxed grains in the composite, and the average grain size distribution ranged from 17.3μm to 22.2μm. The cross-sectional microhardness exhibits an overall increasing distribution from 66 to 128 HV1 from the substrate to the top of the part. It had 360 MPa ultimate tensile strength, 216 MPa yield strength, and 16% elongation in the horizontal direction.
