基于钛合金丝材的增材制造技术研究进展
Research Progress of AM Technology Based on Titanium Alloy Wire
摘要
Abstract
Since the development of metal additive manufacturing(AM)technology,it has been widely used in many fields and has been included in the twelve disruptive technologies that determine the future economy.In recent years,metal wire-based AM technology has become the focus of AM research and application,due to its high deposition efficiency,low manufacturing cost,short manufacturing cy-cle and high material utilization rate.This paper discussed the latest research achievements in optimization of forming process parame-ters,analysis of macrostructure and microstructure,regulation of post-heat treatment microstructure and properties and development of special raw materials in detail,focusing on widely used wire arc additive manufacturing(WAAM),electron beam free form fabrication(EBF3)and laser and wire additive manufacturing(LWAM)based on titanium alloy wire.On this basis,the application of additive man-ufacturing based on titanium alloy wire in engineering and the formulation of relevant standards were introduced.Finally,the paper pointed out the inherent defects of the additive manufacturing technology of titanium alloy wire in terms of structure,properties,etc.,put forward the methods of forging and additive manufacturing hybrid process,composite post-treatment and special wire development,and suggested establishing a new standard system which was different from traditional forging and casting one.The above suggestions were all helpful to promote large-scale applications of the additive manufacturing technology of titanium alloy wire in various fields.关键词
