Abstract Scope |
Additive Manufacturing has become a popular route to create difficult to produce geometries, hard to manufacture materials and a more just-in-time supply chain approach. Additive manufacturing is an integral part of the designer and material scientist toolbox today. The nuclear community is looking to utilize additive manufacturing for in-core components on nuclear materials. T-91 a ferritic-martensitic steel deployed and tested in fast reactor applications is considered for production via AM routes. This work utilizes laser based directed energy deposition methods to build T-91 components. We investigate orientation dependent microstructure and mechanical properties while evaluating the post-production heat treatment schedule needed to achieve desirable properties compared to wrought material. We find minimal orientation effects and rather beneficial properties compared to wrought material, enabling AM-T91 to be used in nuclear applications. |
