Abstract Scope |
In this study, we propose a in-situ homogenization heat treatment of Inconel 718 during induction heating-assisted laser direct energy deposition. In this method, the in-situ homogenization is performed by maintaining the temperature of the deposit at the homogenization temperature for Inconel 718, thereby the total time required for post-heat treatment process could be shortened. In order to investigate the effect of induction heating during the deposition, two thick walls were deposited with and without the induction heating. Additionally, a 3D transient heat transfer model of the deposition process was built to calculate the temperature profiles during the process. The temperature profiles were correlated with the microstructural features of the deposits. Furthermore, an as-deposit sample without induction heating was homogenization heat-treated using furnace and compared with the in-situ homogenized sample. |
