| Abstract Scope |
This work seeks to expedite alloy discovery and design by using combinatorial and high-throughput synthesis and characterization to develop material libraries that link composition with microstructure and mechanical properties. To correlate alloying with changes in material characteristics, binary and ternary Cu, Ni, and Al systems are investigated by co-sputtering films with compositional gradients; over 500 distinct compositions and microstructures are evaluated. Material libraries are generated by characterizing each sample composition using SEM, EDX, XRD, and nanoindentation. To identify compositions of interest and elucidate relationships between material properties, data from the alloy material libraries is analyzed and used to develop new theoretical models and train machine learning models. Using this information, alloys with novel material properties and microstructures are selected and further investigated using TEM. In total, the material property space for a binary and ternary alloy is explored to understand the effects of alloying on material characteristics and microstructure. |
