Tungsten is widely used as a material capable of withstanding extreme operating conditions
and is one of the candidates for use in fusion and Generation IV fission reactors. Atomistic …

In a recent experimental work, as a result of severe plastic deformation, a non-equilibrium
solid solution was obtained despite the very limited solubility of zirconium (Zr) in aluminum …

A crowdion is an interstitial atom embedded in a close-packed atomic row of a crystal lattice,
it is very mobile and efficient in transferring energy and mass during plastic deformation, ion …

During irradiation, bombardment with energetic particles, or plasma treatment, structural
transformations occur in materials, in which point defects play a very important role. Highly …

This study examines the mechanism of nonlinear supratransmission (NST), which involves
the transfer of disturbance to discrete media at frequencies not supported by the structure …

Abstract The supersonic M× N-crowdions are excited in a two-dimensional lattice by giving
sufficiently large initial velocity v to the M× N block of atoms along a close-packed direction …

Among a wide variety of point defects, crowdions can be distinguished by their high energy
of formation and relatively low migration barriers, which makes them an important agent of …

Composite materials are gaining increasing attention from researchers worldwide due to
their ability to offer tailored properties for various technical challenges. One of these …

A molecular dynamics (MD) simulation method is used to investigate the effect of grain
boundary (GB) segregation on the deformation behavior of bicrystals of equiatomic …

We investigate the dynamics of a single magnon excitation in a quantum Heisenberg model
under the effect of lattice vibrations. The Heisenberg spins are set on a nonlinear Morse …
