Kinetics of hydrogen absorption by yttrium dihydride powder

Autor: Yu. M. Filyand, Yu. B. Patrikeev, Yu. V. Levinsky

Publikováno v: Russian Journal of Non-Ferrous Metals. 52:125-127

The kinetics of hydrogen absorption by a powder of yttrium dihydride is investigated. A sample having a known specific surface area and a composition close to the lower concentration boundary of the homogeneity region of dihydride is saturated with h

Variation of the porous structure and leakage currents of anodes of niobium condensers in electrolytic oxidation

Autor: V. I. Bocharova, S. M. Novikova, A. B. Zaitsev, Yu. B. Patrikeev, Yu. V. Levinskii, Ya. M. Polyakov

Publikováno v: Soviet Powder Metallurgy and Metal Ceramics. 30:216-219

Shaping of the anodes results in a large reduction of the total volume and dimensions of the pores. The magnitude of this reduction is determined unambiguously by the dispersion of the initial powder and oxidation voltage. Shaping results in the form

Interrelationship between the properties of powders, the pressing and sintering conditions, and the structure of porous niobium III. The porous structure of material of sintered niobium powders

Autor: A. B. Zaitsev, Yu. V. Levinskii, Ya. M. Polyakov, Yu. B. Patrikeev

Publikováno v: Soviet Powder Metallurgy and Metal Ceramics. 29:530-534

In the initial stage of sintering of high-porosity compacts of niobium powder the average pore size increases, the fine pores disappear, and coarser pores than in the original compacts appear.

Interrelationship between the properties of powders, the conditions of pressing and sintering, and the structure of porous niobium

Autor: Ya. M. Polyakov, Yu. B. Patrikeev, Yu. V. Levinskii, A. B. Zaitsev

Publikováno v: Soviet Powder Metallurgy and Metal Ceramics. 29:197-200

With an increase in niobium powder particle size the pressability increases while the formability decreases. There is a linear relationship between the normalized radius of the pores in high-porosity niobium powder specimens and the normalized volume

Method of assessing diffusion coefficients from gas absorption by metal powders

Autor: V. V. Badovskii, Yu. N. Zaitsev, Yu. M. Filyand, Yu. V. Levinskii, R. V. Bakradze, S. S. Kiparisov, V. V. Tolmachev, Yu. B. Patrikeev

Publikováno v: Soviet Powder Metallurgy and Metal Ceramics. 21:273-279

A simple experimental method is proposed for determining diffusion coefficients from amounts of gas absorbed by metal powders. An analysis is made of errors in the measurement of D by the new method, and optimum experimental conditions are indicated.
