Crystal-geometrical features of the structure of cast and normalized steel with 0.62 % of C content were studied using EBSD method. Inheritance link between the formation of pearlitic and ferritic-pearlitic structures with the structure of intercryst

Electric welding is usually used for surfacing metal products. This process may be laborious and timeconsuming, which at the same time excludes welding jointing throughout the product surface. The productivity of powder tape surfacing is pretty low,

This paper presents a new higher derivative gravity which in spontaneous breaking electroweak symmetry state does not have ghost in gravity sector. We show that Newton constant of the gravity and dark energy density they depend on the fundamental TeV

In the present work we consider the electromagnetic wave equation in terms of the fractional derivative of the Caputo type. The order of the derivative being considered is 0 <\gamma<1. A new parameter \sigma, is introduced which characterizes the exi

In this work we consider a flat cosmological model with a set of fluids in the framework of supersymmetric cosmology. The obtained supersymmetric algebra allowed us to take quantum solutions. It is shown that only in the case of a cosmological consta

The synthesis of MgB2-based materials under high pressure gave the possibility to suppress the evaporation of magnesium and to obtain near theoretically dense nanograined structures with high superconducting, thermal conducting, and mechanical charac
