## Description

- description: Combinatorial alloy design—an economical yet high-throughput alloy
    design approach, facilitates rapid screening of a wide range of compositions with
    limited material expenditure. The ever-growing demand for multi-functional modern
    materials’ necessitates the design of multi-component alloys that can cater to
    the requirements of end application, with targeted properties and ease of synthesis.
    To this end, we report the current trends in combinatorial alloy design approach
    that are available to develop a subset of multi-component alloys, namely high-entropy
    alloy (HEA) in both functionally tailored thin-film form and compositionally optimized
    bulk scale. The thin-film form synthesized by combinatorial magnetron sputtering
    approach enables generation of a library of compositions in a single-step process,
    i.e., developing multiple concentration gradients in a single reference substrate.
    While the identified, best performing compositions from the combinatorial library
    can then be scaled up to bulk form utilizing combinatorial vacuum induction melting
    route for application-oriented design and analysis. As an example, the bulk form
    of multi-component Fe70-xMnxCo10Cr15Cu5 (x = 10, 15, 20 at.%) HEA was developed
    by combinatorial vacuum induction melting route to explore the influence of Mn
    on phase formation and compare the same with calculation of phase diagram (CALPHAD)-based
    theoretical predictions. The hot-rolled alloys were subjected to bulk-scale phase
    analysis using X-ray diffraction, microstructure imaging by scanning electron
    microscopy, and chemical composition analysis by energy-dispersive X-ray spectroscopy
    toward understanding the role of composition on the mechanical property variation
    in the developed alloys. Such a comprehensive approach would facilitate on the
    one hand rapid identification of novel, high-performance alloys, while on the
    other hand support the development of experimentally guided, compositionally tuned
    materials database for future design of multi-component alloys be it by machine
    learning or by conventional methods.
