Structure and Corrosion Resistance Against Intergranular Corrosion of Nickel-based Superalloy VDM ® Alloy C-4

The structure of VDM ® Alloy C-4 (UNS 06455) in “as received” state was studied. The data on the kinetics of secondary phases formation for “sheet” and “tube” samples in the range from 550 to 1100 ∘C after exposure for various period of time (from 30 min to 1000 hours) are presented. The data concerning the resistance against intergranular corrosion of the material under various conditions were analyzed using ASTM G-28 and RD 24.200.15-90 techniques. Keywords: nickel alloy, structure, VDM Alloy C-4, TTP-diagram, intergranular corrosio

Nucleation phenomena of topological closed-packed phases in Fe-Ni-Cr-Mo alloys

В работе изучены механизмы зарождения топологически плотно упакованных фаз в сплавах системы Fe-Ni-Cr-Mo. Показано, что предпочтительными местами зарождения частиц ТПУ фаз являются высокоэнергетичные поверхности раздела. Но также встречаются выделения, зародившиеся непосредственно из аустенитной матрицы.The nucleation phenomena of topological closed-packed phases in Fe-Ni-Cr-Mo alloys were studied. It is shown that the preferred sites of nucleation particles TCP phases are high-energy interface. But there are also particles, which nucleates directly from the austenite matrix.Программа развития УрФУ на 2013 год (п.1.2.2.3

Functioning of the French text in the ethnographic Siberian journals of V. A. Dolgorukov (end of the 19th - beginning of the 20th centuries)

This article is dedicated to the neglected phenomenon of the use of French in Russian-language regional history journals published by V.A. Dolgorukov in the Siberian city of Tomsk. Such issues as the annual Putevoditel’ po Sibiri i Aziatskoi Rossii (“A Guide to Siberia and the Asian Part of Russia”), the monthly journals (Dorozhnik po Sibiri i Aziatskoi Rossii (“A Road Guide to Siberia and Asian Russia”), and Sibirskii nabliudatel’ (“The Siberian Observer”) are analyzed. They contained French texts, translations of Russian texts into French, and translations from French. The theme of the French sections is studied along with particularities of the translations. The principles of the usage of French in pre-revolutionary publications are analyzed

Subband analysis and synthesis of signals

Currently, a wide class of modern wireless telecommunications systems is based on the use of broadband signals. The problems of synthesis for their formation and processing algorithm are extremely important for such systems, especially under the conditions of various types of disturbances, which is impossible without scientifically based analysis of signal propertie

Evaluation of noise immunity of high orbital satellite telecommunication systems with broadband noise-like sign

HIn with this regard article assesses the noise immunity of high-orbit satellite telecommunication systems with code division of addresses when using a number of broadband noise-like signals with linear frequency modulation as information carrier

Decisive rule experimental studies to detect objects on the background of nhe earth surface using polarization differences of radar signals

The task of stationary and moving object detection against the background of the underlying surface (earth) by radar means becomes relevant. A decision rule is being developed to detect objects against the background of the earth surface using the polarization differences reflected from the earth and the objects of radar signals, represented as a measurement vecto

Quick search and synchronization algorithm for wideband noise-like signals

In this regard, the article proposes the fast search and synchronization algorithm for high-orbit satellite telecommunication systems when they are used as the information carriers of broadband noise-like signals with linear frequency modulation. The developed algorithm is based on the consideration of development peculiarities for these signal

Sub-band identification of speech signals word fragments according to given sample

The article considers the problem of the speech signals fragments, generated when pronouncing a certain word form, emphasis in the recordings, which is of the interest from the position of the speech information exchange analysis solvable applied problem. In this case, it is assumed that initially the class of the desired word form is given by the fragment available in the real speech signal recordin

Sub-band invariants of handwritten texts fuzzy fragments

Socio-economic processes informatization is largely implemented by using various documents electronic storage, including scanned handwritten texts or their fragments images, in particular, in the form of officials’ original signatures. Among the very diverse tasks of handwritten documents scans electronic repositories computer analysis, the direction of automatic search for images fragments, that contain outlines of key words of interest, is quite relevant. The search for such fragments is significantly hampered by the variability of the letterforms, even by the same author. Therefore, it is advisable to use a fragment from the analyzed text as an initial sampl
