| Abstract Scope |
Rapidly growing interests in Ti-containing multi-principal element alloys (MPEA), due to their distinct combination of the room- and elevated-temperature mechanical properties and corrosion resistance for a wide range of potential applications, motivated us to analyze the literature data for the Ti-containing MPEAs to unearth the composition-processing-microstructure-property relationships for aeroengine applications. We applied advanced statistical analysis—including principal component analysis (PCA) and hierarchical clustering (HC)—and multiple-attribute decision making (MADM) synergistically to hear the voice of the data. The ranks assigned by several MADMs, including ARAS (additive ratio assessment), ROVM (range of value method), and MEW (multiplicative exponent weighing), were consistent. However, the ranks of the alloys varied by varying the relative weights of various properties, which revealed several MPEAs’ potential to substitute a range of aeroengine parts. The analyses suggest potential replacement substitutes and provide possible directions for the design and improvement of titanium-containing MPEAs. |
