摘要:

電子束熔絲增材制造技術(shù)因其電子束能量密度高、所處真空環(huán)境等優(yōu)勢，逐漸成為金屬增材制造領(lǐng)域的研究熱點之一。回顧了電子束熔絲增材制造技術(shù)的發(fā)展歷程及現(xiàn)狀，介紹了一種新型電子束熔絲增材制造技術(shù)——同軸送絲電子束熔絲增材制造。結(jié)合作者課題組近幾年的研究工作，針對Ti-6Al-4V鈦合金的成形缺陷、顯微組織及力學(xué)性能，對傳統(tǒng)電子束熔絲增材制造技術(shù)和同軸送絲電子束熔絲增材制造技術(shù)進行了對比論述，其中同軸送絲電子束熔絲增材制造有望沉積β晶粒更細(xì)、更等軸的鈦合金構(gòu)件。最后結(jié)合當(dāng)前研究存在的不足，對電子束熔絲增材制造的發(fā)展給出了建議。

Abstract:

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 equiaxed β grains. 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.
