Abstract Scope Titanium-containing high entropy alloys (HEAs) have been investigated for a wide range of potential applications, including elevated temperature, biomedical, extreme environments, and so forth. We analyzed the available data in the literature for the titanium-containing HEAs against the conventional high-temperature materials (CHTMs) for applications in aeroengines to unearth the composition-processing-microstructure-property relationships by materials informatics. We applied fundamental statistical analysis (FSA), principal component analysis (PCA), and multiple-attribute decision making (MADM) to hear the voice of the data. The ranks assigned by several MADMs, including ARAS (additive ratio assessment), MEW (multiplicative exponent weighing) and ROVM (range of value method), were consistent. FSA and PCA consolidated the MADM ranks of the alloys and identified similar top-ranked alloys. The investigations highlight differences (and similarities) among the HEAs and CHTMs and suggest potential replacement substitutes, and provide possible directions for improvement and further development of titanium-containing HEAs.
