Effects of Al and La elements on mechanical properties CoNiFe0.6Cr0.6 high-entropy alloys (HEAs) with face-centered cubic (FCC) structure were investigated by first-principles calculations. The variation curves relevant physical parameters, including lattice constants, formation enthalpy, elastic modulus, Poisson's ratio, Pugh's Cauchy pressure, anisotropy factors, Vickers hardness, yield strength, energy factor, as a function concentration discussed in detail. Results show that the...
Abstract 2D ferromagnets have attracted considerable attention due to their strong potential in the post‐Moore Law era. However, intrinsic ferromagnetic materials typically suffer from suppressed Curie temperature thermal fluctuation, magnetic order instability limit, and others. Herein, a nonmagnetic fluorine modification strategy is proposed control ferromagnetism of air‐stable antimonene. It demonstrated that fluorinated antimonene (F‐antimonene), synthesized via an electrochemical...
Stacking fault energies (SFEs) of Mg solid solutions at different temperatures are very significant for studying dissociation dislocation, plasticity deformation and other mechanical properties. Our present work starts with the investigation interactions between basal stacking faults (SFs) solutes (Li, Cu, Zn, Al, Y Zr) using first-principles calculations. It is found that SFs can be extended to several closed-packed layers. Combined Fermi–Dirac function solute distribution each layer,...
Ceramics show brittle nature because of ionic and covalent bondings. However, the need for reliable high-power applications with vibrational displacements under high electric fields stress loadings demands robust piezoelectric ceramics. In this work, three series Lead Zirconium Titanate-based ceramics are synthesized via solid solution reaction technique. The microstructures phases manipulated by doping different rare-earth oxides Nd2O3, Dy2O3 Yb2O3. Although all as-sintered a perovskite...
The stability and mechanical thermodynamic properties of Al11RE3 intermetallics (RE = Sc, Y lanthanide La-Lu) have been investigated by combining first-principles Debye model calculations. It was found that the formation enthalpies are all negative, indicating they stable; moreover, experimental values Al11La3 Al11Ce3 in good agreement with predicted values, which −0.40 kJ/mol −0.38 kJ/mol, respectively. calculated results reveal Young’s modulus E shear G La, Ce, Pr, Nd Sm) obviously greater...
First-principles calculations within generalized gradient approximation have been performed to investigate ideal strengths of anti-fluorite structured Mg2X (X = Si, Ge, Sn and Pb) compounds. The present showed that the tensile occur in [111] directions while shear appear (111) [11-2] systems. Both strength decreased gradually with increase atomic number X. microscopic process inherent mechanisms mechanical properties were discussed from evolution electronic structures during strain.
Thermodynamic and fracture properties of CrFeCoNiMnx (0 ≤ x≤3) high-entropy alloys (HEAs) are theoretically investigated by first-principles calculations based on density functional theory quasi-harmonic Debye model, the atomic disorder crystal cell is modeled via special quasi-random structure (SQS) approach. In which, alloying element Mn temperature used as control variables, then relevant parameters, e.g., formation energy, vibrational entropy, specific heat capacity, thermal expansion...
Al–Mg–Zn alloys reinforced by T–Mg32(Al,Zn)49 phase had higher structure stability and strength than Al–Zn–Mg–(Cu) MgZn2 phase, but the reasons for these two kind of was not well-known. To reveal discrepancy between T lattice parameters, cohesive energy, electronic as well elastic properties were investigated based on density functional theory. Four types unit cell employed according to symmetry space group. The calculated constants well-agreed with experimental data. Compared phases...
