Cast MoSiBTiC Composites by Metallothermic SHS: Influence of Ti and C Dopants

Autor: Yu. S. Vdovin, D. E. Andreev, V. I. Yukhvid

Publikováno v: International Journal of Self-Propagating High-Temperature Synthesis. 30:153-158

Influence of added Ti + C mixtures on the metallothermic SHS of cast MoSiBTiC composites in the Mo–Si–B system in conditions of artificial gravity (a = 100 g) was explored by SEM/EDS and XRD. With increasing amount of added Ti + C powder blend (u

General Aspects of the Combustion Synthesis of a Cobalt Alloy with Dispersion and Precipitation Modification

Autor: V. I. Yukhvid, D. E. Andreev, N. Yu. Khomenko, K. V. Zakharov

Publikováno v: Inorganic Materials. 57:727-732

We have studied the potentialities of dispersion and precipitation modification of a cobalt alloy in combustion mode under the effect of centrifugal forces. The starting mixture consisted of Co3O4, Cr2O3, Nb2O5, MoO3, and Al, with titanium carbide an

Magnetic-Field-Assisted Preparation of Ferromagnetic Ni–Co–Mn Catalyst for Deep Oxidation/Hydrogenation from a Mixture of SHS-Produced Intermetallics

Autor: S. Ya. Zhuk, E. V. Pugacheva, D. E. Andreev, V. N. Borshch

Publikováno v: International Journal of Self-Propagating High-Temperature Synthesis. 30:106-110

The process of magnetic-field-assisted preparation of ferromagnetic Ni–Co–Mn catalyst for deep oxidation/hydrogenation from a mixture of SHS-produced intermetallics was explored by SEM, XRD, and BET methods. Alkali leaching of precursor powder wa

Tailoring the Composition and Structure of Nb-, Si-, and B-Doped Mo-Based Composite Materials in the Self-Propagating High-Temperature Synthesis Metallurgy Process

Autor: N. V. Sachkova, V. I. Yukhvid, D. E. Andreev, I. D. Kovalev, Yu. S. Vdovin, T. I. Ignat’eva

Publikováno v: Inorganic Materials. 56:1265-1270

We have examined for the first time the feasibility of producing cast Nb-, Si-, and B-doped Mo-based composite materials by a spin-casting self-propagating high-temperature synthesis metallurgy method and obtained new results regarding control over t

Centrifugal Metallothermic SHS of Cast Co–Cr–Fe–Ni–Mn–(Х) Alloys

Autor: D. E. Andreev, Vladimir N. Sanin, V. I. Yukhvid, O. A. Golosova, D. M. Ikornikov

Publikováno v: Russian Journal of Non-Ferrous Metals. 61:436-445

A relatively new approach to obtaining metal materials containing several principal elements in equiatomic concentrations which look promising for replacing commercially used alloys is proposed. Such materials are called high-entropy alloys (HEAs). S
