Presently, the main trend in thin-sheet steel production, including the high-strength automobile steel, is to reduce production costs while retaining essential properties and quality. A considerable part of the cost of high-strength steel comes …

Axial chemical inhomogeneity in metals is a common issue in the production of thick-sheeted products from microalloyed pipe steels. To study the behavior of liquation zones during rolling, a model has been developed to describe and analyze the …

Heat-resistant nickel alloys are promising materials for manufacturing structural elements used in high-temperature nuclear power plants. Nickel alloys are characterized as difficult-to-weld materials; this is one of the main factors limiting …

On the basis of the results of experimental studies aimed at the investigation of the influence of dielectric permittivity of a working liquid on the size characteristics of powders obtained under the conditions of electroerosion metallurgy of the …

The influence of laser welding modes on the structure and properties of butt joints formed for the models of cast sample—cast sample, wrought sample—wrought sample, as well as a hybrid joint of a cast and a wrought sample of Al3Ca0.5La1Mn …

The paper addresses the importance of using aluminum for the production of drill pipes. It also discusses one of the problems associated with the production of drill pipes having a protective thickening (central upset), such as the formation of a …

A method has been proposed to enhance the mechanical properties of hot-finished sintered steels, which consists of additional plastic deformation with a degree of deformation, at which the intracrystalline bonding of the material is preserved. The …

The results of structural studies and assessment of the bending strength of a VKNA-4U alloy based on nickel aluminide are presented. It is for the first time that this alloy was produced by spark plasma sintering of mechanically activated powders …

Laser surface alloying is a method used to modify a metal surface to produce a thin surface layer with improved mechanical properties. The results of tests on surface carburizing and boriding of steel 20 using a laser beam are presented. Before …

The study investigated the effect of retrogression and re-aging (RRA) on the structure and properties of the new Al–3.5Zn–3.5Mg–3.5Cu–1.6Er–0.2Zr–0.2Cr alloy through the use of scanning electron microscopy, thermodynamic calculations, hardness …

At present, the available data on the behavior of osmium in the course of extraction of rhenium from washing sulfuric acid used in the production of copper are extremely limited and contradictory. In this connection, the investigation of its …

The effect of the linear energy input (EL ), varied from 120 to 300 J/m due to a change in the electron beam current (I) from 4 to 20 mA and the scanning speed (v) from 2 to 8 m/s, on residual porosity, aluminum content and local distribution, and …

Nonmetallic inclusions in steel such as oxides, silicates, aluminates, spinels, etc. substantially reduce the quality of metal. They are mainly introduced by the slag formed on the metal surface of a double-strand plant. It is proposed to separate …
