High-entropy alloys (HEAs) with high hardness and high ductility can be considered as candidates for wear-resistant applications. However, designing novel HEAs with multiple desired properties using traditional alloy design methods remains challenging due to the enormous composition space. In this work, we proposed a machine-learning-based framework to design HEAs with high Vickers hardness () and high compressive fracture strain ().

Article Synopsis
  • Superplastic metals, known for their impressive ductility over 300%, are sought after for creating intricate engineering components but face various limitations like low strength and costly processing.
  • Research highlights a high-strength lightweight medium entropy alloy (Ti V Zr Nb Mo) with ultrafine particles that demonstrates superior coarse-grained superplasticity (>440%) at high temperatures and strain rates.
  • This study reveals a unique deformation mechanism that combines dislocation slip, dynamic recrystallization, and grain boundary sliding, paving the way for enhanced superplastic forming techniques and the future development of stronger alloys.

High-entropy alloy coatings (HEAC) exhibit good frictional wear and corrosion resistances, which are of importance for structure materials. In this study, the microstructure, surface morphology, hardness, frictional wear and corrosion resistance of an AlCoCrFeNi high-entropy alloy coating synthesized by atmospheric plasma spraying (APS) were investigated. The frictional wear and corrosion resistance of the coating are simultaneously improved with an increase of the power of APS.
