Title: A comparison study of local lattice distortion in Ni₈₀Pd₂₀ binary alloy and FeCoNiCrPd high-entropy alloy

Abstract

In this paper, the effect of alloying Pd on the local lattice distortion (LLD) in the Ni and FeCoNiCr host matrixes is quantified by integrating local structure characterization and theoretical calculations. The local structure measurements reveal that the mean LLD in the FeCoNiCrPd high-entropy alloy (HEA) is twice as high as the Ni₈₀Pd₂₀ binary alloy though the FeCoNiCr base alloy has a negligible mean LLD. Density functional theory calculations unveil that the unexpected high mean LLD in FeCoNiCrPd is related to the high fluctuation of LLD in the FeCoNiCr matrix. Finally, these observations suggest a synergetic effect of chemical complexity on HEAs' mean LLD.

Evolution of local lattice distortion under irradiation in medium- and high-entropy alloys

Journal Article Tong, Yang ; Velisa, Gihan ; Zhao, Shiteng ; ... - Materialia

Here, a major challenge for future nuclear reactors is to design nuclear materials that can sustain extremely prolonged radiation damage. Local lattice distortion, considered as a core effect of high-entropy alloys (HEAs), can suppress the growth of radiation defects to control radiation performance. However, local lattice distortion in HEAs is rarely quantitatively measured. Here we employed total scattering technique to study the local structure of the face-centered cubic (fcc) equiatomic FeCoNiCr MEA, and FeCoNiCrMn and FeCoNiCrPd HEAs before and after ion irradiation. Their local lattice distortions were quantitatively evaluated based on the difference of lattice constant between the local structuremore »« less

Local structure of Ni₈₀X₂₀ (X: Cr, Mn, Pd) solid-solution alloys and its response to ion irradiation

Journal Article Zhang, Fuxiang ; Tong, Yang ; Velisa, Gihan ; ... - Journal of Physics. Condensed Matter

In this work, the local structure of Ni₈₀X₂₀ (X: Cr, Mn, Pd) solid-solution alloys was investigated with x-ray absorption and total scattering x-ray diffraction methods. Atomic pair distribution function (PDF) analysis indicated that the local lattice distortion is strongly relevant to the atomic size mismatch, and the local lattice distortion in Ni80Pd20 alloy is obviously larger than that in other solid-solution alloys. The bond length of different atomic pairs was derived from the fitting of extended x-ray absorption fine structure spectra. Quantitative analysis of the local bonding environment in Ni₈₀Cr₂₀ during Ni ion irradiation suggested that Cr atoms tend tomore »« less

A precipitation-hardened high-entropy alloy with outstanding tensile properties

Journal Article He, J. Y. ; Wang, H. ; Huang, H. L. ; ... - Acta Materialia

Recent studies indicated that high-entropy alloys (HEAs) possess unusual structural and thermal features, which could greatly affect dislocation motion and contribute to the mechanical performance, however, a HEA matrix alone is insufficiently strong for engineering applications and other strengthening mechanisms are urgently needed to be incorporated. In this work, we demonstrate the possibility to precipitate nanosized coherent reinforcing phase, i.e., L1₂-Ni₃(Ti,Al), in a fcc-FeCoNiCr HEA matrix using minor additions of Ti and Al. Through thermomechanical processing and microstructure controlling, extraordinary balanced tensile properties at room temperature were achieved, which is due to a well combination of various hardening mechanisms, particularlymore »« less

Influence of non-magnetic Cu on enhancing the low temperature magnetic properties and Curie temperature of FeCoNiCrCu(x) high entropy alloys

Journal Article Chaudhary, Varun ; Soni, Vishal ; Gwalani, Bharat ; ... - Scripta Materialia

The microstructure and magnetic properties of three face-centered cubic (FCC) FeCoNiCrCu(x) high entropy alloys (HEAs) (x=0, 0.5, 1) are investigated. Interestingly, addition of the nonmagnetic element Cu to FeCoNiCr HEA is found to enhance exchange interactions and low temperature saturation magnetization. The paramagnetic to ferromagnetic Curie transition temperature increases from 85 K for FeCoNiCr to 118 K for FeCoNiCrCu. This is counterintuitive since Cu is nonmagnetic; however, atom probe tomography revealed Cu rich clusters containing 5 at% Ni and 1 at% each of Fe, Co, Cr, within FCC matrix, these clusters altered the matrix composition and consequently its magnetic properties.
