Abstract Scope |
This work seeks to expedite alloy discovery by using combinatorial and high-throughput synthesis and characterization to develop material libraries that link alloy composition, microstructure, and mechanical properties. To correlate alloying with changes in material characteristics, binary and ternary alloys are investigated by co-sputtering thin films with compositional gradients, creating 169 distinct samples per sputtering run. Material libraries are generated by characterizing each sample’s composition, morphology, texturing, and mechanical properties. To identify compositions of interest and elucidate relationships between material properties, data from the material libraries is analyzed and used to train machine learning models. Using this information, alloys with novel material properties are selected and further investigated using TEM. In total, the material property space for a ternary alloy is explored and compared to binary alloys in order to understand the effects of alloying on material characteristics and microstructure. |
