It is established that the rate??and completeness of the oxidation of aluminum increase if it is alloyed with cerium.??The e?ect of cerium is due to its polyvalence, high reactivity, and surface activity??toward aluminum. Structural and phase nonuniformities that arise during the growth??of oxide phases on the surface of oxidized particles of the alloys enhance the interaction??of these particles with air oxygen. It is shown that the assumptions that the surfaces??of the alloys have a micrononuniform structure and are enriched with CeAl2 and CeAl4??groups are valid \\\\Expert2\\nbo\\Combustion, Explosion, and Shock Waves\\2001, V. 37, N 4, p.413-417.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ОКИСЛЕНИЕ -- МЕТАЛЛЫ ПОРОШКОВЫЕ -- НАГРЕВАНИЕ -- ПОРОШКИ АЛЮМИНИЕВЫЕ Аннотация: It is shown that the oxidation of alumln1~m- powders and rare-earth elements as the temperature rises is accompanied by cracking of a layer of interaction products at the particle surface. The intensity of cracking is reflected in the change of the specific powder surface during heating, and it depends on the phase formation in the barrier layer and its physicochemical properties. The real oxidation rate of disperse metals is higher than the diffusion rate in oxides, which indicates the determining role of cracking in the interaction mechanism \\\\Expert2\\nbo\\Combustion, Explosion, and Shock Waves\\1998, V. 34, N 1, p. 40-43.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ПОРОШКИ ЛАНТАНА -- ТЕРМОГРАВИМЕТРИЯ -- ОКСИД ЛАНТАНА -- НАГРЕВАНИЕ Аннотация: Thermogravimetric, d i f f e r e n t i a l - t h e r m o g r a p h i c , chemical, and x-ray phase analysis methods are used to study the effect of the rate at which powdered lanthanum is heated in air on the nature of the reaction products. It is found that for heating rates of up to 150 K/rain the interaction with air ends in the formation of lanthan~m oxide. At heating rates of 150-600 K/rain, a nitride phase is formed along with LazO3. Further increases in the heating rate lead to formation of the oxide phase only. The reasons for this behavior of lanthanum are examined. \\\\Expert2\\nbo\\Combustion, Explosion, and Shock Waves\\1999, V. 35, N 1, p.77-79.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): АЛЮМИНИЙ -- КАРБИД ТИТАНА -- РЗМ -- РЕДКОЗЕМЕЛЬНЫЕ ЭЛЕМЕНТЫ Аннотация: The wetting of titanium carbide by molten Al–rare earth alloys was studied. The physicochemical properties of the alloys were correlated with the contact angle and the carbon and oxygen affinities of the substrate and alloy. The properties of the alloys were investigated as a function of composition. The phase relations in the Al-rich corners of the Al–Y and Al–Nd phase diagrams were refined using viscosity data. The x-ray microanalysis and Auger electron spectroscopy data were used to assess the melt structure, adsorption behavior of the melt components at the liquid–gas and liquid–solid interfaces, interfacial area, and composition of the transition layer. The introduction of rare-earth additions into Al was found to reduce the temperature at which good adhesion to TiC can be achieved by 100–200 K |
