The Mechanism of Grain Boundary Serration and Fan-Type Structure Formation in Ni-Based Superalloys
A model of discontinuous precipitation of γ′ phase at grain boundaries (GBs) in polycrystalline Ni-based superalloys during continuous cooling from supersolvus temperature was developed. The model calculates the ...

Magnetic susceptibility of multilayered carbon nanotubes
A theoretical study of the magnetic susceptibility of multilayered carbon nanotubes in fields both parallel, H ∥, and perpendicular, H ⊥, to the tube axis has been carried out disregarding electron-electron inter...
