Abstract Scope |
Titanium alloys find diverse aerospace applications owing to their superior combination of lightweight, mechanical properties, corrosion resistance, and so forth. We analyzed the available data, in the literature, of the titanium alloys for two critical applications: landing gear beams and aeroengines. We applied fundamental statistical analysis (FSA), principal component analysis (PCA), and multiple-attribute decision making (MADM) to unearth the voice of the data. The ranks assigned by several MADMs, including ARAS (additive ratio assessment method)), 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 similarities (and differences) across several grades/variants of the alloys, suggest potential replacement or substitute for the existing alloys, weed-out some of the heavier alloys and consequently help in reducing the weight, and provide possible directions for improvement and/or development of these alloys. |
