High strength dual fcc phase CoCuFeMnNi high-entropy alloy wires with dislocation wall boundaries stabilized by phase boundaries

Data supporting the hierarchically activated deformation mechanisms to form ultra-fine grain microstructure in carbon containing FeMnCoCr twinning induced plasticity high entropy alloy

“…1 (e) exhibit a misorientation angle around 2-18°. On the other hand, deformation twins in large grains exhibited a misorientation angle of 60° with respect to the fcc matrix [3] Fig. 1 .…”

“…1 d high KAM values appeared in the regions of slip bands and twin boundaries (TBs) which related to the high local strain in the regions enclosed by the slip bands and TBs. Based on definition of misorientation, is considered as a low angle grain boundaries (LAGB) and is considered as a high angle grain boundaries (HAGB) [2 , 3] . The point-to-origin and point-to-point misorientation angle profiles of deformation bands in Fig.…”

Microstructural Stability of the CoCrFe2Ni2 High Entropy Alloys with Additions of Cu and Mo

“…On the other hand, large positive values may induce separation between the added element and Cu, which at the same time will not avoid Cu segregation. This was described in [41,42], where the reduction in the enthalpy of the mixing in combination with the strain energy is suggested to be the driving force for phase separation. This selecting criterion also explains the good microstructural behavior of CoCrFeNi systems after adding V and Mn, with ∆H f orm = 13 and 29 meV/atom, respectively [40], as experimentally observed in [15,35].…”

Microstructures of FeCoNiMo and CrFeCoNiMo Alloys, and the Corrosion Properties in 1 M Nitric Acid and 1 M Sodium Chloride Solutions

“…This concept is widely used to develop new alloys with good mechanical properties [6,7]. Additionally, the properties of high-entropy alloys can be improved by deformation [8,9]. Many alloys with good corrosion resistance are thus studied and developed, because corrosion is a major problem in the application of metals.…”
