AbstractLiV308 powder has been prepared on a large scale by spray drying ofan aqueous gel. The material was further dehydrated at 150 and 350ºC. These materials were characterized by TGA, XRD and electrochemical methods. Materials dried at 150 and 350ºC, showed an unusual high reversible capacity, close to 4 Li per formula unit, and cycle well. The material dried at 350ºC is very similar to the crystalline LiV308 prepared by conventional high temperature synthesis.

The investigating results are shown on the V‒Al alloy nitriding while burning in the large-scale reactor. The nitriding optimal condition were defned. The phaseforming behavior was investigated while the V‒All alloy nitriding under the burning condition. The processing method was developed for the self-propagating hightemperature nitriding. The test batch of the nitrided V‒ Al‒N alloy was manufactured.Ill.5. Ref. 5.

Currently, metal–matrix composite materials are some of the most promising types of materials, and they combine the advantages of a metal matrix and reinforcing particles/fibres. Within the framework of this article, the high-temperature synthesis of metal–matrix composite materials based on the (Ni-Ti)-TiB2 system was studied. The selected approaches make it possible to obtain composite materials of various compositions without contamination and with a high degree of energy efficiency during production processes. Combustion processes in the samples of a 63.5 wt.% NiB + 36.5 wt.% Ti mixture and the phase composition and structure of the synthesis products were researched. It has been established that the synthesis process in the samples proceeds via the spin combustion mechanism. It has been shown that self-propagating high-temperature synthesis (SHS) powder particles have a composite structure and consist of a Ni-Ti matrix and TiB2 reinforcement inclusions that are uniformly distributed inside it. The inclusion size lies in the range between 0.1 and 4 µm, and the average particle size is 0.57 µm. The obtained metal-matrix composite materials can be used in additive manufacturing technologies as ligatures for heat-resistant alloys, as well as for the synthesis of composites using traditional methods of powder metallurgy.
