Hot compression behaviors and microstructure evolutions of a cast dual-phase NiCoFeCrAl0.7 high-entropy alloy

Hot Deformation Characteristics and Microstructure Evolution of CoCrFeNiZr0.3 Hypoeutectic High-Entropy Alloy

“…Wang et al [29] investigated the hot compression behavior and organization evolution of dual phase NiCoFeCrAl 0.7 HEA, and the relationship between the flow stress and the thermal compression parameters is established by the constitutive equation. The activation energy of the dual phase HEA was significantly improved up to approximately 379.81 kJ/mol.…”

Complex dynamic restoration processes leading to a high degree of deformability in a dual-phase Al0.5CoCrFeNi high entropy alloy

“…However, their work lacks microstructural analysis after deformation is carried out, and underlying deformation mechanisms were not identified. Wang et al [47] investigated hot compression behavior and microstructure evolutions of a cast dual-phase NiCoFeCrAl 0.7 alloy containing 79.2 vol% fcc and 20.8 vol% bcc phases compressed to a true strain of 0.5 at a temperature range 900-1100 ºC and strain rate range 10 −3 -10 −1 s −1 . It was found that the continuous DRX mechanism within the fcc phase governs the flow softening of the alloy during hot compression.…”
