Journal ArticleDOI
Mechanical Properties and Stacking Fault Energies of NiFeCrCoMn High-Entropy Alloy
TL;DR: In this article, the stacking fault energy of two-to-five-component equiatomic alloys has been determined from x-ray diffraction measurements using first-principles electronic structure calculations.
Journal ArticleDOI
A Novel Low-Density, High-Hardness, High-entropy Alloy with Close-packed Single-phase Nanocrystalline Structures
TL;DR: A low-density, nanocrystalline high-entropy alloy, Al20Li20Mg10Sc20Ti30 was produced by mechanical alloying as discussed by the authors, which formed a single phase fcc structure during ball milling and transformed to single phase hcp upon annealing.
Journal ArticleDOI
The evolution of the deformation substructure in a Ni-Co-Cr equiatomic solid solution alloy
Jiashi Miao,C.E. Slone,Timothy M. Smith,Changning Niu,Hongbin Bei,Maryam Ghazisaeidi,George M. Pharr,Michael J. Mills +7 more
TL;DR: In this paper, the authors investigated the origin of the exceptional properties of NiCoCr alloy, which are related to the evolution of the deformation substructure with strain, interrupted tensile testing was conducted on the equiatomic NiCo-Cr single-phase solid solution alloy at both cryogenic and room temperatures at five different plastic strain levels of 1.5, 6.5%, 29, 50% and 70%.
Journal ArticleDOI
Magnetically-driven phase transformation strengthening in high entropy alloys
TL;DR: It is shown that a nanostructured phase at lattice defects in CoCrNi causes its extraordinary properties, while it is magnetically frustrated and suppressed in CrMnFeCoNi.
Journal ArticleDOI
Spin-driven ordering of Cr in the equiatomic high entropy alloy NiFeCrCo
Changning Niu,A.J. Zaddach,A. A. Oni,Xiahan Sang,J. W. Hurt,James M. LeBeau,Carl C. Koch,Douglas L. Irving +7 more
TL;DR: In this paper, the spin-driven ordering of Cr in an equiatomic fcc NiFeCrCo high entropy alloy (HEA) was predicted by first-principles calculations.
