| Abstract Scope |
Combinatorial high-throughput synthesis methods are one of the most promising methods to produce materials libraries sufficiently fast to provide the large experimental datasets that machine learning approaches require. Therefore, developing high-throughput, accurate, and alloy-agnostic synthesis techniques is a key enabler for ML-informed design of alloys where experimental data can be scarce. To address this, current work aims to establish a high-throughput methodology, using direct energy deposition and ex-situ mixing of elemental powders. This approach is demonstrated by the synthesis and characterisation of Co-Al-W and Al-Ni-Co systems, which present significant processing challenges due to large differences in elemental melting points and sensitivities to elemental segregation. The method is evaluated through the quantification of achievable compositional accuracy, the samples' homogeneity and the rate at which samples can be produced. Results presented provide insight into the viability of elemental powder-based systems for high-throughput experimental data production. |
