摘要
增材制造技术可实现复杂钛合金零件的成形,因此在航空、航天、船舶等领域的应用日益广泛.热等静压具有独特的热压耦合作用,使其能够在改善组织结构的同时,消除零件内孔缺陷,因此,逐渐被应用于增材制造零件的组织性能调控.本研究简述了钛合金增材制造件在组织、缺陷和性能上的特点,以及热等静压相对传统热处理技术在组织、缺陷和性能调控上的优势,为热等静压技术在钛合金增材制造件后处理过程中的应用提供了依据.
Abstract
The utilization of additive manufacturing has made it easier to manufacture intricate titanium alloy components,con-sequently leading to their widespread adoption in fields like aviation,aerospace,and shipbuilding.The unique thermal-mechan-ical coupling effect of hot isostatic pressing allows it to improve the microstructure and eliminate internal porosity defects in com-ponents,which is why it is gradually being used for the organizational performance control of additive manufacturing parts.In this study,a concise overview of the microstructure,defects,and performance of additive by manufactured titanium alloy parts is carried out,as well as the advantages of hot isostatic pressing over traditional heat treatment techniques in terms of micro-structure,defects,and performance regulation.The study discovery lays the groundwork for employing hot isostatic pressing technology in the post-treatment procedure of titanium alloy parts produced by additive manufacturing.
