Variation of orbital symmetry of the localized 3d^1 electron of the V^{4+} ion upon the metal-insulator transition in VO_2 [PDF]
The Physics of Metals and Metallography, Vol. 94, No. 1, 2002, pp.
17-23, 2003 The electronic structure of the vanadium dioxide VO_2 in the tetragonal R and two monocinic M_1 and M_2 structural modifications was calculated in frames of the local-density functional (LDA) approach and the LSDA + U formalism of correction for correlation effects. Based on the results of calculation, we argue in favor of the Mott-Hubbard mechanism of

Fretting Fatigue Life Model Under Combined Loading
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 1, Page 16-30, January 2025.ABSTRACT This paper evaluates the capability of the theory of critical distances (TCD) coupled with the Fatemi–Socie (FS), Smith–Watson–Topper (SWT), and normal stress range (S‐N) criteria for the lifetime estimation of combined fretting fatigue, that is, the combination of bending and axial loading modes, for 316L stainless steel along with the effect

Features of formation of the Al-Cu single crystals structure under the action of pressure and gravitational field on the crystallization process [PDF]
arXiv, 2008 X-ray structural and spectral analyses, X-ray diffraction topography and metallography were used to study dendrite structure of Al-4 wt % Cu single crystals grown by the Bridgman technique at a rate of 1 mm/min and on seeds with <001> orientation. The single crystals were obtained upon the crystallization of the melt under the action of a pressure and ...
