Ultrasound velocity measurements in high-chromium steel under plastic deformation

In the present study, the variation of the propagation velocity of ultrasound in the plastic deformation of corrosion-resistant high-chromium steel 40X13 with ferrite-carbide (delivery status), martensitic (quenched) and sorbitol (after high-temperature tempering) structures have beem studied/ It is found that each state shows its view of the loading curve. In the delivery state diagram loading is substantially parabolic throughout, while in the martensitic state contains only linear strain hardening step and in the sorbitol state the plastic flow curve is three-step. The velocity of ultrasonic surface waves (Rayleigh waves) was measured simultaneously with the registration of the loading curve in the investigated steel in tension. It is shown that the dependence of the velocity of ultrasound in active loading is determined by the law of plastic flow, that is, the staging of the corresponding diagram of loading. Structural state of the investigated steel is not only changing the type of the deformation curve under uniaxial tension, but also changes the nature of ultrasound speed of deformation

Stress-strain state and loss of stability of anisotropic thermal coating under thermal shock

The deformation behavior of thermal barrier coatings has been investigated. The mechanism of occurring instabilities in such coatings based on their representation in the form of a plate located on an elastic foundation has been studied. Loss of stability manifests itself in the form of a doubly periodic system of intrusion and extrusion zones that is qualitatively consistent with the well-known experimental results. Typical features of stability loss and its dependence on the properties of conjugated materials have been investigated by the example of the thermal loading simulation of the copper specimen with a protective ceramic coating. The influence of the thermo-mechanical properties anisotropy of the coating material on the character of the emerging instability has been estimated

Research of the plastic flow of electrolytically saturated with hydrogen (He) Al-Cu-Mg alloy

The effect of hydrogen embrittlement on the plastic flow of Al-Cu-Mg alloy was investigated (HE). The studies were performed for the test samples of aluminum alloy subjected to electrolytic hydrogenation in a three electrode electrochemical cell. It is found that the mechanical properties and plastic flow curves of aluminum alloy are affected adversely by HE. These are found to show all the plastic flow stages: the linear, parabolic and pre-failure stages. It is established that the hydrogenation enhances the localization of straining leads to significant changes in the characteristics distances between local straining zones. The patterns of localized plasticity appear to be useful for a detailed analysis of plasticity exhibited by aluminum alloys

The effect of hydrogen embrittlement on the mechanical properties of aluminum alloy

The effect of hydrogen embrittlement on the mechanical properties of aluminum alloy D1 was investigated. The studies were performed for the test samples of aluminum alloy subjected to electrolytic hydrogenation. It is found that the mechanical properties of aluminum alloy are affected adversely by hydrogen embrittlement. The hydrogenated counterpart of alloy has a lower degree of ductility relative to the original alloy; however, the plastic flow behavior of material remains virtually unaffected. The deformation diagrams were examined for the deformed samples of aluminum alloy. These are found to show all the plastic flow stages: the linear, parabolic and pre-failure stages would occur for the respective values of the exponent n from the Ludwik-Holomon equation. Microhardness tests were performed for as-treated aluminum alloy D1; the measurement results are presented

Pioneers of the Nuclear Industry in the Urals: V. F. Turusin

The creation of the domestic nuclear industry, which celebrates its 75th anniversary in 2020, was of exceptional importance for our country and largely determined its post-war history. Thanks to the nuclear industry, nuclear parity was achieved in a short time, which became a guarantee of protection from a global catastrophe, and the state’s defense capability was ensured. In this jubilee year for the industry, it is especially important to pay tribute to the pioneers, whose work and talent created the country’s nuclear power. The article is dedicated to one of the pioneers of the nuclear industry - VF Turusin, who devoted his entire career to the Mayak chemical plant (now the Mayak production association) and to the city of nuclear scientists - Ozersk.Создание отечественной ядерной промышленности, которая в 2020 г. отмечает 75-летний юбилей, имело исключительное значение для нашей страны и во многом определило её послевоенную историю. Благодаря атомной отрасли в короткие сроки был достигнут ядерный паритет, ставший гарантией защиты от глобальной катастрофы, обеспечена обороноспособность государства. В юбилейный для отрасли год особенно важно отдать должное первопроходцам, трудом и талантом которых создавалась ядерная мощь страны. Статья посвящена одному из первопроходцев атомной отрасли – В. Ф. Турусину, посвятившему всю свою трудовую деятельность химкомбинату «Маяк» (ныне –производственное объединение «Маяк») и городу атомщиков – Озерску.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 20-09-00103 «Индустриальный Урал и советский атомный проект: экономические и экологические последствия функционирования ядерно-промышленного комплекса в регионе (1945–1991 гг.)»

Heterogeneity of plastic flow of bimetals electrolytically saturated with hydrogen

This paper presents the study of a corrosion-resistant bimetal composed of austenitic stainless steel (301 AISI) and low-carbon construction steel (A 283 Grade C) and the effect of its electrolytic hydrogenation on plastic flow of the test material. Localization patterns of plastic deformation in the process of uniaxial tension were obtained using the digital image correlation method. The evolution of localized plastic deformation zones was studied in the initial state and after electrolytic hydrogenation. The staging of stress-strain curves was analyzed
