Abstract

Language:

Wire + Arc Additive Manufacturing (WAAM) can be used to create large free-form components out of specialist materials such as nickel-base superalloys. This study investigates Inconel (IN) 718, a nickel-based superalloy known for its excellent weldability, which makes it suitable for the WAAM process. The objective of this research was to examine the influence of post-deposition heat treatments on the microstructure and tensile properties of WAAM IN 718. A modified heat treatment process was conducted, focusing on the dissolution of the Laves phase without precipitating the δ phase. Using elevated temperature tensile tests, the results indicated that post-deposition heat treatments effectively altered the grain structure, resulting in reduced anisotropy in tensile properties at elevated temperatures. Although the elevated temperature tensile properties of WAAM IN 718 met the minimum specifications for cast materials, they did not reach the standards set for wrought materials. This research contributes to understanding the effects of heat treatments on WAAM produced components, highlighting potential applications in industries requiring high-performance materials.
