WebDec 24, 2024 · Wang et al. showed that CrFeCoNi can undergo plastic deformation to high strains, with deformation by dislocation motion, and the operation of work hardening mechanisms at a significant rate, stemming from the low stacking fault energy (approximately 30 mJ/m 2 despite the content of Ni ). In contrast, around indents in … WebEvident cracks were observed in the Al0.8CrFeCoNi HEA coating. Meanwhile, when x = 0.25, the cracks disappeared, but the bonding shear strength was 79.6 MPa, only 34.7% of the substrate. At 0.5 ≤ x ≤ 1, the bonding shear strength of the Al0.8CrFeCoNiCuxHEA coatings went above 175.2 MPa.
