Abstract Scope |
The present work focuses on the densification and distortion behaviour of Inconel 718 parts fabricated using the laser powder bed fusion (LPBF) technique. A three-dimensional (3D) Finite Element Modeling of LPBF was developed using ANSYS software to predict the unsteady temperature distribution, solid ratio, microstructure, and distortion. The melt pool characteristics in size and the porosity in LPBF processed Inconel 718 were investigated at the 3D component level. The melt pool characteristics developed with both single-track and multi-track were evaluated. It was found that melt pool characteristic is critical for densification behaviour. The results show densification behaviour depending on the melt pool size and reference width. This result is explained based on the solid ratio. LPBF processed Inconel 718 samples were achieved when the solid ratio = 1. Further, these results help gain insight into the temperature distribution for a comprehensive understanding of the distortion in the 3D-built part. |
