Regressional Analysis of Lattice Parameters in the Cantor Alloy

High Entropy Alloys (HEAs) are a novel class of materials with several (often 5 or more) elements alloyed together at approximately equiatomic ratios, unlike traditional alloys with one primary element and small proportions of additive elements. These alloys have shown potential for better mechanical and functional properties than traditional alloys. The chemical complexity of HEAs makes it impossible for experimentalists to fully sample the compositional phase space, but this also creates an opportunity for novel analytical methods. Perhaps the most studied HEA is the original Cantor alloy (CrMnFeCoNi). In this work, we collate published experimental measurements to form an exhaustive dataset of lattice constants for Cantor alloys across varying compositions. We discuss the challenges of accumulating this data set and data mining methods we have used to identify papers containing the required information. In addition, we report the results of regression analyses to understand trends in the lattice constants with composition.
