The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
Matrix Microstructure and Its Micro-Analysis of Constituent Phases in As-Cast Fe-Cr-C-V Alloys
(Japan Inst Metals, Sendai, 2009)
The as-cast matrix microstructure in 19 mass%Cr-2.8 mass%C white cast iron with up to 4.7 mass% V additions has been studied. Type and degree of the austenite transformation in the course of cooling after solidification ...
The effect of Y2O3 addition on thermal shock behavior of magnesium aluminate spinel
(International Institute for the Science of Sintering, Beograd, 2009)
The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel has been investigated. As a starting material we used spinel (MgAl2O4) obtained by the modified glycine nitrate procedure (MGNP). ...
The Influence of Powder Particle Size on Properties of Cu-Al2O3 Composites
(International Institute for the Science of Sintering (IISS), 2009)
Inert gas atomized prealloyed copper powder containing 2 wt.% Al (average particle size approximate to 30 mu m) and a mixture consisting of copper (average particle sizes approximate to 15 mu m and 30 mu m) and 4 wt.% of ...
Improvement of Ethanol Fermentation of Corn Semolina Hydrolyzates with Immobilized Yeast by Medium Supplementation
(University of Zagreb, 2009)
The possibilities of improving ethanol fermentation of enzymatically obtained corn semolina hydrolyzates with alginate-immobilized yeast Saccharomyces cerevisiae var. ellipsoideus by medium supplementation with mineral ...
