Effect of Calcium Microalloying on the Service and Corrosion Properties of V1341 Alloy SheetsPleiades Publishing Ltd - Tập 2021 - Trang 672-678 - 2021
O. E. Grushko, B. V. Ovsyannikov, M. A. Gureeva
The influence of calcium microalloying on the texture of aluminum Al–Mg–Li and Al–Mg–Si–Cu alloys is studied. The paper considers the mechanical properties at static and dynamic loads, the fatigue characteristics, the crack resistance, and the high-temperature strength of V1341 alloy sheets with a regulated recrystallized structure in state T1. The properties of the sheets are also determined afte...... hiện toàn bộ
Effect of High Temperatures on the Mechanical Properties of 09G2S SteelPleiades Publishing Ltd - Tập 2021 - Trang 492-495 - 2021
S. A. Nikulin, S. O. Rogachev, S. G. Vasil’ev, V. A. Belov, Yu. A. Nikolaev
The structure and mechanical properties of 09G2S steel are studied during uniaxial tension tests in the temperature range from room temperature to 1200°C. The temperatures above which the strength properties of the steel decrease are determined. Austenite grain growth is shown to be very weak in the temperature range from room temperature to 1000°C.
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.
Relation between the Hardness and the Strength of Gray Cast Iron with Allowance for the Structural ParametersPleiades Publishing Ltd - Tập 2017 - Trang 984-988 - 2018
A. A. Baron, L. V. Palatkina
The factors that affect the relation between ultimate tensile strength σu and hardness HB of gray cast iron with flaked graphite are studied. The scatter of the ultimate tensile strengths at a given hardness is shown to be caused by one of the primary structure parameters, namely, the volume fraction of primary austenite dendritic crystals. The dependences derived in this work can be used to incre...... hiện toàn bộ
Phase composition of Al–Ti–Nb–Mo γ alloys in the heat-treatment temperature range: Calculation and experimentPleiades Publishing Ltd - Tập 2015 - Trang 576-584 - 2015
N. A. Belov, N. I. Dashkevich, S. O. Bel’tyukova
The phase composition of TNM-type Al–Ti–Nb–Mo γ alloys at heat-treatment temperatures is quantitatively studied using the Thermo-Calc program package and experimental methods. Isothermal cross sections are calculated and the joint influence of two alloying elements on the phase composition of the alloy is determined at the mean concentration of a third component. Based on the calculations of verti...... hiện toàn bộ
