Researchers have reported a relatively simple and inexpensive method of enhancing metal powders for additive manufacturing by adding ceramic nanowires
Researchers from the Istanbul University of Technology in TÃ¼rkiye and the Massachusetts Institute of Technology (MIT) reported that adding ceramic nanowires is relatively simple and inexpensive to strengthen metal powders.
“For extreme environments, we always need to develop more capable materials. We believe that this method has enormous potential for other materials in the future,” said Ju Li, a nuclear engineering professor at the Battell Energy Alliance and a professor at MIT’s Department of Materials Science and Engineering (DMSE).
The team’s approach began with Inconel 718, a popular high-temperature alloy. Researchers used a small number of ceramic nanowires to grind commercial Inconel 718 powder, resulting in the uniform decoration of nanoceramics on the surface of Inconel particles. Then, the obtained powder is used for additive manufacturing of parts through laser beam powder bed melting (PBF-LB).
Inconel 718 alloy is a nickel-based high-temperature alloy widely used in various fields due to its excellent high-temperature strength, oxidation, and corrosion resistance. In the field of additive manufacturing, the application of Inconel 718 alloy mainly involves the following aspects:
Inconel 718 alloy is widely used in additive manufacturing to manufacture high-performance aerospace components, such as aircraft engines and turbine components.
Inconel 718 alloy is also used in additive manufacturing to manufacture key components in the energy sector, such as corrosion-resistant components in petroleum and chemical equipment, fuel rod jackets, steam generators in nuclear reactors, and solar collector tubes.
Inconel 718 alloy is also used in additive manufacturing to manufacture automotive engine components, such as exhaust systems and turbochargers.
In addition to the fields above, Inconel 718 alloy is also used in additive manufacturing for key component manufacturing in other fields, such as medical devices, chemical reactors, and furnaces.
