Abstract Scope |
Over the last two decades, high-entropy materials, including high-entropy alloys (HEA), have gained importance due to their superior ambient- and elevated-temperature mechanical properties, including wear, thermal properties, and degradation resistance. We compiled and analyzed the HEA literature data for forging die applications. We applied multiple-attribute decision-making (MADM), viz. Simple additive weighting (SAW), Range of value method (ROVM), Measurement of alternatives and ranking according to compromise (MARCOS), Weighted Euclidean distance-based approach (WEDBA), Combined compromise solution (CoCoSo), and so on, for sorting and ranking the alloys; the ranks assigned by several MADMs were consistent. Principal component analyses (PCA) consolidated the ranks and generated the rank charts, while hierarchical clustering (HC) discerned the similarities among the alloys. The investigation identifies top HEAs for coating on conventional H13 or 4340, or Uddeholm dievar substrate hot forging dies and suggests directives to promote and develop high-performance materials for industrial applications applying the high-entropy concept. |
