摘要

影响增材制造零件最终显微组织的因素很多。在粉末床熔化(PBF)工艺中，如选择性激光熔化(SLM)和电子束熔化(EBM)，其中一个因素是零件的构建方向。为了研究零件取向的影响，通过EBM制造了一组样品。显微组织和显微硬度表征表明，如果在特定应用中力学性能的均匀性至关重要，则组件的垂直取向可能是更好的，但它可能会增加制造时间。

Effect of Build Orientation in Electron Beam Melting of Ti-6Al-4V Specimens

There are many factors influencing the final microstructure of additively manufactured parts. In Powder Bed Fusion (PBF) processes like Selective Laser Melting (SLM) and Electron Beam Melting (EBM), one of such factors is a build orientation of a part. To investigate an effect of the part orientation a set of samples have been manufactured via the EBM. The microstructure and microhardness characterization showed that vertical orientation of the components could be preferable if homogeneity of mechanical properties is critical for the particular application, but it may increase the manufacturing time.
