Frequency Dependence of Microwave Giant Magnetoresistive Effect in the Magnetic Metallic Nanostructures
Physics of Metals and Metallography - Tập 120 - Trang 333-338 - 2019
D. V. Perov, A. B. Rinkevich
A numerical analysis of the frequency characteristics of the giant magnetoresistive effect in magnetic metallic nanostructures has been performed. It has been shown that there are two limiting cases, when the parameters of the microwave giant magnetoresistive effect differ strongly. In particular, at frequencies of the centimeter and millimeter ranges of electromagnetic waves for the metallic magn... hiện toàn bộ
Magnetic domains in martensite of the Ni-Mn-Ga alloy
Physics of Metals and Metallography - Tập 101 - Trang 446-449 - 2006
V. V. Kokorin, S. V. Dubinko, O. M. Babii, A. R. Prokopov
Structural changes that accompany an intermartensitic transformation in the Ni-Mn-Ga alloy have been considered. The magnetic domain structure of martensite in this alloy has been also studied with the help of optical microscopy using indicator films of iron garnet. A labyrinthine domain structure has been detected.

Regularities of recrystallization of rolled single crystals and polycrystals of zirconium and alloy Zr-1% Nb
Physics of Metals and Metallography - Tập 115 - Trang 756-764 - 2014
M. G. Isaenkova, Yu. A. Perlovich, V. A. Fesenko, O. A. Krymskaya, N. A. Krapivka, Soe San Tkhu
Features of processes of recrystallization in rolled single crystals and polycrystals of zirconium and alloy Zr-1% Nb have been analyzed. To estimate the crystallographic texture and structural state of the materials under study, diffractometric X-ray methods have been used. It has been found that the α-Zr matrix regions that were deformed with the preferential participation of twinning are charac... hiện toàn bộ
The microstructure of a magnetically hard Zr2Co11 alloy
Physics of Metals and Metallography - Tập 107 - Trang 270-275 - 2009
G. V. Ivanova, N. N. Shchegoleva
Electron-microscopic and electron-graphic analysis has demonstrated that the Zr2Co11 compound has a complex structure. All grains consist of thin plates of a high-temperature rhombohedral phase, which are parallel to the (0001) crystallographic plane; the crystal lattices in the neighboring regions have a twin orientation relative to each other. The transformation of the rhombohedral phase into a ... hiện toàn bộ
Microstructure and technological plasticity of cast intermetallic alloys on the basis of γ-TiAl
Physics of Metals and Metallography - Tập 109 - Trang 402-410 - 2010
V. Imayev, T. Khismatullin, R. Imayev
This work is devoted to the estimation of the technological plasticity of binary and alloyed γ titanium aluminides by conducting compression tests at T = 1000°C. The technological plasticity was shown to grow with decreasing size of grains and grain colonies and with increasing amount of β-stabilizing elements in the alloys. The best technological properties are characteristic of the alloys that s... hiện toàn bộ
Hyperfine-interaction parameters and magnetic phase antiferromagnet–ferromagnet transition in Ce(Fe1–x Si x )2
Physics of Metals and Metallography - Tập 117 - Trang 1185-1191 - 2016
A. V. Vershinin, S. P. Naumov, V. V. Serikov, N. M. Kleinerman, N. V. Mushnikov, V. S. Rusakov
Mössbauer spectroscopy study of Ce(Fe1–x Si x )2 compounds with x = 0 and 0.07 was performed at different temperatures. Easy magnetization axis of the CeFe2 ferromagnet at 130 K was shown to be in the {110} plane and to deviate from the [001] axis by ∼10°. Upon cooling, the Ce(Fe0.93Si0.07)2 compound undergoes the ferromagnet–antiferromagnet phase transition in a temperature range of 120–125 K, wh... hiện toàn bộ
Reorientation of Hydrides in Unirradiated Clad Tubes Made of Alloy E110 under Conditions Simulating Long-Term Dry Storage of Spent Nuclear Fuel
Physics of Metals and Metallography - Tập 122 Số 9 - Trang 861-868 - 2021

The Effect of High-Temperature Thermomechanical Treatment on the Microstructure and Mechanical Properties of Cu–Al–Ni–(B) Alloys with a Thermoelastic Martensitic Transformation
Physics of Metals and Metallography - Tập 124 - Trang 710-718 - 2023
A. E. Svirid, V. G. Pushin, V. V. Makarov, N. N. Kuranova
Polycrystalline boron-alloyed α + β Cu–Al–Ni compositions subjected to high-temperature thermomechanical treatment (HTMT) via forging and rolling are studied for the first time. Optical, scanning, and transmission electron microscopy and X-ray diffraction analysis were used in combination with measurements of tensile mechanical properties to study the peculiarities of the microstructure, phase com... hiện toàn bộ
Structure, mechanical, and tribotechnical properties of an austenitic nitrogen steel after frictional treatment
Physics of Metals and Metallography - Tập 118 - Trang 399-406 - 2017
N. A. Narkevich, I. A. Shulepov, Yu. P. Mironov
The features of the structure and the mechanical and tribotechnical properties of an austenitic nitrogen steel (Cr16.5, Mn18.8, C0.07, N0.53, Si0.52 wt %, and Fe for balance) after frictional treatment have been studied. It has been shown that, along with twinning, the nitrogen austenite upon frictional treatment undergoes a γ → stacking fault → ε transformation. The strengthening of the steel by ... hiện toàn bộ
