Abstract Scope |
Nuclear applications, especially advanced nuclear, are among the most challenging environments for materials. Stress, temperature, time, nuclear properties and radiation damage all are required boundary conditions a material needs to fulfill in order to be useful in a nuclear application. These restrictions limit the design space of materials, especially considering nuclear properties in addition to the physical properties.
Additive Manufacturing allows for near net shape fabrication of engineering structures while also changing the material on a single component reducing the need for conventional dissimilar joints. In this presentation we show examples of chemically graded components and thermodynamic modeling prediction of expected phases as well as expand the grading approach towards heat treatment to tailor the microstructure as needed. The combinations of modeling, and printing graded materials provide an alternative to address some of the materials selection challenges. |
