摘要
电子束熔丝增材制造技术因其电子束能量密度高、所处真空环境等优势,逐渐成为金属增材制造领域的研究热点之一。回顾了电子束熔丝增材制造技术的发展历程及现状,介绍了一种新型电子束熔丝增材制造技术——同轴送丝电子束熔丝增材制造。结合作者课题组近几年的研究工作,针对Ti-6Al-4V钛合金的成形缺陷、显微组织及力学性能,对传统电子束熔丝增材制造技术和同轴送丝电子束熔丝增材制造技术进行了对比论述,其中同轴送丝电子束熔丝增材制造有望沉积β晶粒更细、更等轴的钛合金构件。最后结合当前研究存在的不足,对电子束熔丝增材制造的发展给出了建议。
Wire-feed electron beam additive manufacturing is becoming popular in metal additive manufacturing due to its advantages of high energy density and vacuum protection.In this paper,the up-to-date research and development of wire-feed electron beam additive manufacturing are reviewed,with a novel coaxial electron beam wire feeding additive manufacturing introduced.In this review manuscript,the process-induced defects,microstructures,and mechanical properties of Ti-6Al-4V alloy fabricated by conventional wire-feed electron beam additive manufacturing and this novel coaxial electron beam wire feeding additive manufacturing are compared and discussed.Coaxial electron beam wire feeding additive manufacturing is expected to deposit Ti alloy components with finer and more equiaxedβgrains.Finally,combined with the main problems of the research status,the future development of wire-feed electron beam additive manufacturing technology is suggested and forecasted.
