Abstract Scope |
In recent years, wire and arc additive manufacturing (WAAM) attracted more and more attention to fabricate Ti components due to its high deposition rate. Multiple thermal cycles from the process create a microstructure gradient, which may significantly deteriorate the mechanical properties of the components. Therefore, it is important to understand the microstructure evolution during the thermal cycling in WAAM process. In the current study, a high-quality Ti-6Al-4V thick wall was deposited by the GMAW-based WAAM process. Gleeble thermal-mechanical simulator was applied to simulate additive manufacturing thermal cycles. Microstructures at the same targeted location experienced multiple thermal cycling were characterized after each thermal cycle. The hardness and electrochemistry corrosion resistance before and after each thermal cycle are also tested. The correlation between microstructure, hardness, and corrosion resistance are established. |
