| Abstract Scope |
Conventional methods of alloy discovery are very time-consuming and expensive, especially for challenging material systems such as superalloys. Material libraries that allow the measurement of bulk material properties can significantly accelerate alloy design efforts. Surface remelting of specimens of varying compositions in contact with each other can be used to create a composition gradient through intermixing, and therefore produces such bulk material libraries. Herein, Laser surface-remelting was employed to create bulk material libraries of the CrCoNi system, as a model system for a superalloy γ-phase composition. Average intermixing distances of approximately 4 mm were achieved, resulting in well-defined composition gradients. Microstructure and mechanical properties were determined and related to the local composition. The material library was used as a proof-of-concept to identify phase boundaries and verify solid-solution-strengthening models in the fcc single-phase region. In summary, the potential for accelerated structural material discovery is demonstrated. |
