CHARGE CARRIERS STATES IN A MODEL OF CuO SUPERCONDUCTIVE CERAMICS

The translational symmetry of the distribution of atoms (ions) of the charge carriers (electrons or holes)system is broken by sputtering (doping) due to the existence of two boundary surfaces. This is a modelof high-temperature superconductors in which the observed symmetry breaking orthogonal to the CuOplane is treated as a perturbation. Single-pa...

THE EFECT OF DIMENSIONALITY AND CURRENT STRENGHT ON CONDUCTIVITY OF GRANULAR METALS

Metallic materials in granular packings show different electrical properties from their bulk counterparts.In this paper, we investigate the temporal evolution of the electrical conductivity of granular metals. Weuse metallic beads arranged in different one-, two- and three-dimensional ensembles through whichdifferent constant currents are injected....

EFFECT OF CHROMIUM CONTENT ON MECHANICAL PROPERTIES OF NICKEL-FREE AUSTENITIC STAINLESS STEELS

This study investigated the mechanical properties of a series of Fe-Cr-Mn (Mo)-N alloys. The chromiumcontent ranged from 16 to 18 mass%. The test alloys were produced by adding nitrided ferroalloys duringmelting in an induction furnace. Test specimens of each alloy were prepared for mechanical testing andmicrostructural observation. Tensile strengt...

EFFECT OF PRECIPITATION HARDENING ON MICROSTRUCTURE OF 17-7 PH STEEL WITH MODIFIED CHEMICAL COMPOSITION

Steel 17-7PH is austenitic-martensitic steel with high strength, hardness, and resistance to creep, andcorrosion. It is designed for aerospace components, but can also be used for other applications that requirehigh strength and corrosion resistance, as well as leaf springs for operation at temperatures up to 316 °C. Itcan be used in a solution...

THE INFLUENCE OF MANGANESE ON THE TENSILE STRENGTH OF HIGH CARBON STEEL C66D

Modern steel production cannot be imagined without manganese, because almost all steels containmanganese.In this paper, we present the impact of manganese on the tensile strength values of high-carbon steel.This paper presents an improvement in the quality of wire rolling with control of manganese content insteel and the value of C-equivalent, in i...
