摘要

电弧增材制造技术因较高沉积效率和较低制造成本，在制造大型钛合金构件方面具有一定优势。首先介绍了电弧增材制造技术的特点，然后重点概述了电弧增材制造 T–6Al–4V 组织、拉伸性能和疲劳裂纹扩展调控进展：（1）成分过冷调控（添加形核质和调整成形工艺参数等）、塑性变形和热处理等对构件组织和拉伸性能的影响；（2）微观组织、裂纹扩展路径和残余应力对构件疲劳裂纹扩展行为的影响。最后，阐述了电弧增材制造 Ti–6Al–4V 所面临的挑战。

Abstract

Wire arc additive manufacturing (WAAM) provides a new method for large titanium alloy components due to its low cost and short production cycle. In the present paper

the WAAM technologies was introduced briefly. Then the research progress in structure

tensile properties and fatigue crack growth of WAAMed Ti–6Al–4V was reviewed. The effects of constitutional cooling regulation (adding heterogeneous nucleation

controlling deposition parameters etc.)

plastic deformation and heat treatment on structure and tensile properties was summarized. The effects of microstructure

fatigue crack growth path and residual stress on the behavior of fatigue crack growth was analyzed. Finally

the challenges of WAAMed Ti–6Al–4V were explained.
