Introduction Recently, high-entropy alloys (HEAs) have attracted increasing attentions because of their unique compositions, microstructures, and adjustable properties [1–31]. They are loosely de?ned as solid solution alloys that contain more than ?ve principal elements in equal or near equal atomic...
High entropy alloys (HEAs) are new class of metallic materials with five or more principal alloying elements. Due to this distinct concept of alloying, the HEAs exhibit unique properties compared to conventional alloys. The outstanding properties of HEAs include increased strength, superior wear resist...
This thesis will focus on single phase high entropy alloys and their ab initio calculation. It will discuss the principal points of the ab initio theory and the theory of alloys including thermodynamics and quantum mechanics. First, it will introduce the results for the metals what are included ...
In this work, the mechanical characteristics of high-entropy alloy Co20Cr26Fe20Mn20Ni14 with low-stacking fault energy processed by cryogenic and room temperature high-pressure torsion (HPT) were studied. X-ray diffraction, scanning electron microscopy (SEM), and transmission electron microscopy (TEM...
Evolution of Microstructures and Properties of the AlxCrCuFeNi2 High-Entropy Alloys The microstructure and Vickers hardness of the AlCrCuFeNi(x=0.5, 1.0, and 2.0 in molar ratio) high-entropy alloys with as-cast and heat-treated states were... S Ma,Z Chen,Z Yong - 《Materials Science Foru...
The new (Zn,Mg,Ni,Fe,Cd)Fe2O4 high entropy ferrite with average crystallite size 11.8 nm was synthesized in two stages by annealing of co-precipitated amorphous precursor. The dielectric spectroscopy confirms, that the electrical conductivity and polarization processes are associated with the mob...
The AlCrFe2Ni2(MoNb)x multiphase high entropy alloys were designed, prepared and characterized. The synergistic effect of Mo and Nb alloying on microstructures and mechanical properties of AlCrFe2Ni2-based high entropy alloy were investigated. By synergistic alloying with Mo and Nb, the volume ...
room-temperaturetensile strengthand total elongation of the alloy were as high as 1103 MPa and 18.7%, respectively, which were better than those of a majority of as-cast high entropy alloys. The new alloy has a potential application in industry and will promote the further study of EHEAs....
