Abstract Scope |
While additive manufacturing of monolithic materials, e.g., metals or ceramics, has seen significant recent progress, the development of the additive manufacturing of composite materials for structural application is still at its early stage. Developing a fundamental understanding of the process-microstructure-property relationships for advanced/additive processes is a critical step toward a further proliferation of this class of materials in critical applications. Here we use a solid-state additive process, namely, cold spray, to fabricate free-standing Ni-CrC composites. We use advanced microstructural and mechanical characterizations, including electron microscopy, in-situ high-energy X-ray diffraction, and computed tomography, to study this material's microstructure and mechanical response. In particular, we focus on the phase-specific response and discuss the load partitioning and load transfer between the two phases of Ni-CrC composites during loading. We find different mechanistic responses under tension and compression. We explore post-spray modifications to optimize the mechanical behavior of the Ni-CrC composites. |
