ABSTRACT

Wire arc additively manufactured components fabricated with the use of titanium and its alloys have extensively gained awareness in biomedical, marine, and aerospace industries owing to their mechanical properties, biocompatibility, and excellent corrosion resistance properties. Post-processing is an essential technique used for fine-tuning microstructure and material properties, correcting incurred errors, and improving surface properties of wire arc additive manufacturing (WAAM)–processed Ti-6Al-4V alloy to enhance the quality of metallic parts. In recent times, several post-processing manufacturing techniques have been fully developed to mitigate the effect of internal flaws formed during the printing of additive manufacturing parts. In this chapter, the significant influence of hot isostatic pressing, heat treatment techniques, machining process, and surface modification techniques as they enhance the structural integrity performance of WAAM-processed Ti-6Al-4V components are fully documented. This chapter systematically reviews the recent progress in post-processing techniques as they improve the material properties of Ti-6Al-4V components produced by the WAAM process.
