Research progress on heat treatment regulation and mechanical properties of selective laser melted γ″-strengthened nickel-based superalloys by NI Xiaoqing, DAI Kunjie, KONG Decheng

“…Therefore, it is imperative to clarify the inherent relationship between the metastable precipitate characteristics in non-equilibrium thermal cycles during the additive manufacturing and the heat treatment processes, such as grain growth, second-phase precipitation, and dislocation evolution during the thermal treatment. The γ″ strengthening nickel-based high-temperature alloys (IN718 alloy) were focused in this paper, which were widely used in the fields of aviation engines and gas turbines, the research progress on the microstructure characteristics after laser selective melting forming was discussed, and the microstructure evolution and variation laws of the mechanical properties after heat treatment were reviewed to explore the methods for regulating the microstructure and improving the mechanical properties of high-temperature alloys under the rapid solidification, and to further expand the application of laser additive manufacturing technology in hot-end structural materials, such as aviation engines and gas turbines.…”

Effect of Printing Orientation Angle and Heat Treatment on the Mechanical Properties and Microstructure of Binder-Jetting-Printed Parts in 17-4 PH Stainless Steel by Iacopo Bianchi, Archimede Forcellese, Pietro Forcellese, Tommaso Mancia, Chiara Mignanelli, Michela Simoncini, Tommaso Verdini

“…Scanning electron microscopy with energy dispersive X-ray spectroscopy was used to observe the fracture surfaces and microscopical defects on the binder jetting printed parts to evaluate the fracture mechanisms. It was demonstrated that printing orientation angles do not affect the mechanical properties of 3D-printed parts, while a significant improvement in the microstructure and mechanical properties is observed after the H900 heat treatment.…”
