Nanoengineering of inorganic and hybrid composites
(Materials Science Forum, 2000)
The engineering of materials and devices on the nanometer scale is of considerable current interest in electronics, optics, catalysis, ceramics and magnetic storage. Different methodologies of processing that lead to the ...
Effect of fibre waviness on compression failure of cross-ply carbon/epoxy laminates
(Materials Science Forum, 2000)
Composites were made as cross-ply laminates with artificially introduced waviness near the middle, with different severity of waviness and different fractions of wavy layers. The laminates had configuration (0/(90 0(2))(n) ...
Thermal stability and kinetic studies of new cobalt(III) complexes with a tetraazamacrocyclic and dithiocarbamate ligands
(Materials Science Forum, 2000)
The thermal properties of four cobalt(III) complexes with cyclam (1,4,8,11-tetraazacyclotetradecane) and the heterocyclic dithiocarbamates Rdtc(-) [2-, 3-, 4-methylpiperidine (2-, 3-, 4-Mepipdtc(-)) or 4-thiomorpholine ...
Stability of chromium(III)-oxide sol in the presence of inorganic anions
(Materials Science Forum, 2000)
Stability of chromium(III)-oxide sol upon the addition of various electrolytes (chloride, sulfate, and ferrocyanate) was studied by a potentiometric titration method. The critical coagulation concentration was determined ...
Determination of the activation energy of nucleation and grain growth in Ni-P metallic glass
(Materials Science Forum, 2000)
Using DSC, we have studied the crystallization kinetics of Ni-P metallic glasses By the Transmission electron microscopy (TEM) image, we have determined the condition of early nucleation saturation in the NI-P crystallization ...
Microstructure and mechanical properties of ZA27 alloy matrix composites
(Materials Science Forum, 2000)
ddThe effect of Al2O3 and SiC particles on microstructure and strength (compression) of ZA27 (zinc-based alloy) was studied. Two composites were produced by compocasting process, i.e. particles of strengtheners were ...
The preferred orientation of bright copper deposits
(Materials Science Forum, 2000)
The preferred orientations of copper deposits obtained from acid sulfate solutions were examined. Mat deposits obtained in the absence of the additives and in the presence of disodium 2-naphthol-3,6-disulfonic acid possessed ...
Dispersion stability of SiC, SiCN and Si3N4 ultrafine powders in aqueous and nonaqueous media
(Materials Science Forum, 2000)
A successful colloidal processing of ultrafine powders to produce high quality ceramic materials gives demand for stable, high degree particle dispersions. The stability of ceramic suspensions on the basis of SiC, Si3N4 ...
The influence of the aging time of RuO2 sol on the electrochemical properties of the activated titanium anodes obtained by sol-gel procedure
(Materials Science Forum, 2000)
The influence of the aging time of RuO2 sol on the electrochemical properties and behaviour in chlorine evolution reaction of RuO2/Ti and (40%RuO2 + 60%TiO2)/Ti anodes obtained by sol-gel procedure was studied. The ...
Tensile characteristics of carbon fibres
(Materials Science Forum, 2000)
In single filament tensile tests with different gauge length, the macromechanical tensile properties of carbon fibres (strength, failure strain and modulus) have been determined. By calculating system compliance, the ...
