Control of electromagnetic stirring by power focusing in large induction crucible furnacesPleiades Publishing Ltd - Tập 2011 - Trang 1152-1155 - 2012
V. E. Frizen, F. N. Sarapulov
An approach is proposed for the calculation of the operating conditions of an induction crucible furnace at the final stage of melting with the power focused in various regions of melted metal. The calculation is performed using a model based on the method of detailed magnetic equivalent circuits. The combination of the furnace and a thyristor frequency converter is taken into account in modeling.
Photometric Analysis of Structure–Strength Properties RelationshipsPleiades Publishing Ltd - Tập 2021 - Trang 1081-1084 - 2021

The modern technologies of mechanical and heat treatment of metals and alloys are based on understanding of organic relationship between the physicomechanical properties of materials and their structural state. It is difficult to express the mechanical properties of materials in the form of contribution of individual structural constituents due to complexity of simultaneous evaluation of all param...... hiện toàn bộ
Aluminum-matrix composite materials with shungite rock fillersPleiades Publishing Ltd - Tập 2010 - Trang 1063-1071 - 2011

A method is proposed for the introduction of shungite rocks into aluminum melts by mechanical mixing with carriers, namely, aluminum granules and reactive titanium powders taking part in exothermic in situ reactions. The structures of composite materials with shungite rock additions are studied, and a stabilizing effect of these additions on dry sliding friction is revealed.

The deformation characteristics of silica fabric with a thermal barrier coating, which is used for the production of the ballute-type aerobrake of a descent module, are estimated. A rubberized fabric strip is subjected to uniaxial tensile tests to failure. Various finite-element simulation approaches to the deformation of the fabric are considered.
Influence of a Zinc Coating on the Mechanical Properties of a Low-Carbon Steel Microalloyed with NiobiumPleiades Publishing Ltd - Tập 2019 - Trang 436-441 - 2019

The mechanical properties of a 08GBYu sheet steel ((wt %) 0.08 C, 1.0 Mn, 0.04 Nb, 0.04 Al) with a zinc coating and after its electrolytic removal are studied. The mechanical properties of the galvanized steel are shown to change insignificantly in the strain rate range from 8.3 × 10–5 to 25 × 10–3 s–1. The fatigue limit under repeated tension is 400 MPa. The strength properties and the fatigue li...... hiện toàn bộ
Statistical Study and Prediction of the Mechanical Properties of Deformed Titanium Alloy Semifinished ProductsPleiades Publishing Ltd - - 2024

The mechanical properties of deformed semifinished products made of titanium alloys manufactured at different enterprises in the period from the 1970s to the present time are studied. The statistical dependences of the standard mechanical properties on the chemical composition, structure, annealing conditions, and test temperature are revealed from the generalization of the published data and resu...... hiện toàn bộ
One-zone rolling of composite materialsPleiades Publishing Ltd - Tập 2016 - Trang 1303-1307 - 2017
L. S. Kokhan, Yu. A. Morozov, Yu. B. Slavgorodskaya
The energy–force parameters of free rolling of a strip without its tension and rolling with one backward or forward creep zone in the deformation zone are compared. The limiting backward or forward tensions are determined, and the change in the linear sizes of a composite billet during deformation in a rolling mill is considered.
