| Abstract Scope |
There is a big need for materials that can resist high temperatures, particularly in the aerospace and nuclear industries. Research clearly shows that oxide nanoparticles, when spread in the base material, make it much stronger at high temperatures, especially for nickel-based alloys.
In parallel, additive manufacturing, and particularly LPBF-LB, provides unique capacities to elaborate optimized design and fucntionalities of components.
The proposed study looks at developing nickel-based alloys that are made stronger by adding oxide. Two base materials are selected for their initial properties in each field: The ABD900® is perfect for the aerospace industry, and the Ni20Mo base is ideal for nuclear applications (such as molten salt reactors). Different techniques for adding nano-oxides to the metal powder of the base alloy (two techniques involving mechanical mixing and a third using a liquid salt route) are investigated. The presentation discusses the microstructure of the manufactured samples and their mechanical properties. |
