| Abstract Scope |
Minimizing the buy-to-fly ratio of aircraft structural parts made from milled Ti-6Al-4V is an important step in reducing the environmental impact of the aerospace industry. One possible way to achieve this goal is through wire arc additive manufacturing (WAAM).
In this work, samples with different cooling rates, achieved by using air curtains, and various widths were investigated. The samples were analyzed in terms of their microstructure and mechanical properties using Scanning Electron Microscopy, tensile and compression tests, in order to establish a correlation between process parameters, microstructure and mechanical properties. Effects of the wall thickness and varying cooling rates and thus the influence of the intrinsic heat treatment on the microstructure and mechanical properties were evaluated. These results highlight the importance of comprehensively understanding the impact of thermal management on the production of Ti‑6Al‑4V components. |
