Investigation into the influence of the interlayer temperature on machinability and microstructure of additively manufactured Ti-6Al-4V

Abstract The capability of wire and arc additive manufacturing (WAAM) to produce large, near-net-shaped parts with inexpensive equipment has led the process being considered as one options significantly decrease buy-to-fly ratio in aircraft manufacture. Even so, there are several challenges associated process: achieving mechanical properties microstructure similar wrought material, well low surface quality parts. is usually improved by milling. As microstructure, here too question arises whether comparable milling material. A significant factor influencing according literature interlayer temperature during WAAM process. Therefore, objective this research was study influence on machinability additively manufactured Ti-6Al-4V. Consequently, first determined for Ti-Al6-V4-parts three different temperatures. Then, macro- microstructures were analyzed and, finally, determined. Contrary expectations based state art, not influenced temperature. This aligns microstructures, which only slightly affected
