The lattice distortion
WebAttractive functionalities have been reported in some bulk HEOs, which are attributed to the long-range compositional homogeneity, lattice distortion, and local chemical bonding characteristics in materials. WebOct 12, 2024 · Abstract. One of the founding concepts of the high-entropy alloy (HEA) field was that the lattice structures of multicomponent solid solution phases are highly distorted. The displacement of the constituent atoms, away from their ideal locations (local lattice strain), has been widely cited as the reason for a number of the observed physical ...

WebSep 11, 2024 · Lattice distortion is one of the four core effects responsible for the unprecedented mechanical behaviors of high-entropy alloys (HEAs). Lattice distortion in HEAs has been investigated in experiments and estimated in theory. In this review, we focus on the lattice distortion based on available ab initio calculations.
WebCorrelated ultrafast spectroscopy performed at the same carrier density as ultrafast electron diffraction reveals that the creation of a dense electron–hole plasma triggers the relaxation of lattice distortion at shorter timescales by modulating the crystal cohesive energy. Finally, we show that the interaction between carrier gas and lattice ...
WebLattice distortion (microstrain) represents departure of atom position from an ideal structure. Crystallite sizes covered in line-broadening analysis are in the approximate range 20–1000 Å.
