| Abstract Scope |
Additive manufacturing (AM) offers new possibilities to fabricate refractory alloys, with unique opportunities for microstructural control. Designing refractory alloys that are amenable to the AM process while retaining application-relevant properties remains a significant challenge. Here, we present high-throughput experimental and computational approaches to develop guidelines for mitigating crack defects in AM processes. By screening hundreds of alloys at the single melt track scale, design principles have been generated for refractory alloys of varying chemical complexities. The role of interstitials in cracking, segregation and precipitation mechanisms will be discussed for select alloys. Altogether, the results presented here establish how AM can broaden the refractory alloy design space. |
