Abstract: Interest in high-throughput studies has grown as we integrate computational tools like machine learning and artificial intelligence in the alloy development process. Functionally graded samples, which have gradual variations in their composition or structure, enable greater efficiency in characterization of alloy chemistries. In this study, we use horizontal sputter deposition to fabricate 200 um compositionally graded lightweight and refractory alloys with bulk-like microstructures. Using this approach, we will evaluate the effects of mechanical deformation on precipitation strengthening in two different material systems: Al-Mg and Ti-V. We aim to demonstrate both the viability of this technique for fabricating bulk samples and how deformation can be used to induce greater precipitation strengthening. The research will evaluate the effects of chemistry, annealing, and deformation on mechanical properties to illustrate how this fabrication method facilitates high-throughput studies.
