The Structure and Properties of Boride Coatings Depending on the Porosity of Powder Steel Preforms
Soviet Powder Metallurgy and Metal Ceramics - Tập 53 - Trang 417-422 - 2014
G. A. Baglyuk, S. G. Pyatachuk, A. A. Mamonova
Metallographic and X-ray diffraction analyses are used to examine the structure of boride coatings produced by saturation of iron and iron–carbon blanks with different porosities at 1000 and 1100°C and microhardness distribution along their depth is analyzed. It is shown that the thickness of the oxide layer increases with the original porosity of the blanks, but its density and surface microstruc...... hiện toàn bộ
High-temperature oxidation of the nitrides of the Groups IV and V transition metals
Soviet Powder Metallurgy and Metal Ceramics - Tập 14 - Trang 562-566 - 1975

Some relationships governing initiation of self-propagating synthesis in direct electric heating
Soviet Powder Metallurgy and Metal Ceramics - Tập 27 - Trang 813-816 - 1988
V. Ya. Belousov, A. V. Pilipchenko, L. D. Lutsak
Self-propagating high-temperature synthesis with direct passage of current through the powder mixture is characterized by various forms of reaction initiation. Taking into account the general features, three types of initiation were detected: contact, breakdown, and volume. These types operate in all the examined powder mixtures, depending on the heating conditions, the preparation quality of the ...... hiện toàn bộ
Effect of annealing on the structure and phase composition of high-dispersion powder irons modified with organic silicon compounds

Thermodynamics of Interaction of Rare-Earth Metals with d-Metals. The Scandium ― Iron System
Soviet Powder Metallurgy and Metal Ceramics - Tập 40 - Trang 354-361 - 2001
Larisa V. Goncharuk, Vladislav R. Sidorko
Gibbs free energies, enthalpies, and entropies of formation of the compounds ScFe2 and Sc29Fe6 are found by measuring the emf of galvanic cells in the range 720-1030 K. The nature of interaction in Fe ― REM binary systems is analyzed. Scandium is shown to behave like a 3d-metal during interaction with iron.
Ferroelectric Thin Films and Multilayer Structures Based on Them
Soviet Powder Metallurgy and Metal Ceramics - Tập 39 Số 7 - Trang 345-354 - 2000
Glinchuk, Maya D.
A brief review is presented of the results of recent research into ferroelectric films and their multilayer structures. The main attention is paid to theoretical calculation of the physical properties that characterize ferroelectric materials (electric polarization, phase transition temperature, dielectric response) in thick and thin films and their multilayer structures. Within the phenomenologic...... hiện toàn bộ
Wettability of Calcium Fluoride by V-, Nb-, and Cr-Containing Liquid Alloys
Soviet Powder Metallurgy and Metal Ceramics - Tập 41 - Trang 72-75 - 2002
Vitalii P. Krasovskii, Yurii V. Naidich
The wetting of calcium fluoride by liquid metal alloys containing 10-50 mass% of chemically active metals (vanadium, niobium, and chromium) was studied by the sessile drop method in vacuum at 700-1350°C. At temperatures above 900°C these alloys did not wet calcium fluoride. The wetting angle was above 90deg;. This is explained by the formation of volatile reaction products at the interface between...... hiện toàn bộ
Successive impregnation of sintered low-carbon iron-base alloys with carbon and chromium
Soviet Powder Metallurgy and Metal Ceramics - Tập 17 - Trang 187-191 - 1978
F. G. Lovshenko, Z. M. Lovshenko, V. T. Vysotskii
Sintering behavior and strength properties of stomatological porcelain—Titanium nickelide composite materials
Soviet Powder Metallurgy and Metal Ceramics - Tập 37 - Trang 369-372 - 1998
N. A. Shevchenko, V. I. Itin
The sintering behavior and strength properties of stomatological porcelain—titanium nickelide composites were investigated. The dependence of porosity, linear and volumetric changes, phase composition and structure on sintering time and temperature, component concentrations, and initial porosity have been determined. It was shown that density changes are the result of a co...... hiện toàn bộ
