Lattice Quantum Chromodynamics close to the light cone [PDF]

, 2008
We use near light cone coordinates in order to establish a Wilsonian lattice formulation of Yang-Mills theories which can be extrapolated onto the light cone.

Lattice Parameter Evolution during the β-to-α and β-to-ω Transformations of Iron- and Aluminum-Modified Ti-11Cr(at.%)

Crystals
β-titanium (β-Ti) alloys are useful in diverse industries because their mechanical properties can be tuned by transforming the metastable β phase into other metastable and stable phases.

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Non-Overlapping Arrangement of Identical Objects: An insight for molecular close packing [PDF]

In this study, we investigate the arrangement of identical objects to achieve non-overlapping configurations, a fundamental challenge across various scientific and engineering disciplines, particularly in the context of molecular close-packing.

Three-particle forces in the lattice dynamics of some hexagonal close-packed metals [PDF]

, 1994
A lattice dynamical model is developed by applying the Clark–Gazis–Wallis-type three-particle forces in the hexagonal close-packed (hcp) system. The model is then applied in the study of the phonon dispersion in four hep metals, namely, Be, Tb, Ho, and ...

Tensoresistive properties of heterogeneous film materials based on refractory metals [PDF]

Журнал нано- та електронної фізики, 2009
We present the experimental investigation results of the tensoresistive properties of heterogeneous film systems based on Re or Fe oxide phases and the metal component of hcp-Re (hcp is the hexagonal close-packed lattice) or a-Mo (a is the amorphous ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Modeling Dislocation Cutting of γ′ Precipitates in Ni‐Base Superalloys: Linking Atomistic and Dislocation Dynamics Simulations

Advanced Engineering Materials, EarlyView.
Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

Modulating phonon dynamics: tailoring lattice vibrations to enhance thermoelectric efficiency in Mg3(Sb, Bi)2 alloy

Nature Communications
Heat in crystalline materials is transported by phonons from lattice vibrations, and lattice thermal conductivity critically determines thermoelectric performance.
