摘要

电子束熔化成形技术（EBM）具有成形速度快、能量利用率高和真空环境无污染等优点，适合于Ti–6Al–4V钛合金的制备，在航空航天、生物医疗等领域得到广泛应用。然而，EBM 成形Ti–6Al–4钛合金构件仍然存在的内部孔隙、粗糙的表面和残余拉应力等缺陷，严重影响了成形件的疲劳性能。通过工艺参数的优化及后处理工艺，如热等静压和表面处理等，可以显著改善 EBM成形件的疲劳性能。综述了EBM成形 Ti–6Al4V钛合金的成形工艺、微观组织、力学性能和典型的应用现状。重点讨论了影响疲劳性能的因素，并总结了一些提高疲劳性能的后处理方法。最后对EBM技术未来的发展前景进行了展望。

Abstract

Electron beam melting (EBM) has the advantages of high forming speed

high efficiency

and no pollution in vacuum environment. It is suitable for forming Ti–6Al–4V titanium alloy and has been widely used in aerospace

biomedical and other fields. However

the internal pores

rough surface and residual tensile stress of the asbuilt EBM Ti–6Al–4V titanium alloy components seriously affect the fatigue performance of formed part. Through optimization of printing parameters and post-treatment processes

such as hot isostatic pressing and surface treatment

the fatigue performance of EBM formed parts can be significantly improved. The forming process

microstructure

mechanical properties and typical application status of EBM Ti–6Al–4V titanium alloy are reviewed. The factors affecting fatigue performance are discussed

and some post-treatment methods to improve fatigue performance are summarized. Finally

the future development prospect of EBM technology is prospected.
