The austempering study of alloyed ductile iron
(Materials and Design, 2006)
Austempered ductile iron (ADI) proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties can ...
Preparation of basalt-based glass ceramics
(Journal of the Serbian Chemical Society, 2003)
Local and conventional raw materials-massive basalt from the Vrelo locality on Kopaonik mountain-have been used as starting materials to test their suitability for the production of glass-ceramics. Crystallization phenomena ...
Effect of LiYO(2) addition on sintering behavior and indentation properties of silicon nitride ceramics
(International Journal of Materials Research, 2006)
The influence of the sintering additive LiYO(2) (5-15 wt.%) on sintering behavior, microstructure and mechanical properties of Si(3)N(4) ceramics was investigated. Since LiYO(2) enables densification of Si(3)N(4) at ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Materials Science Forum, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Sintering of Si3N4 with Li-exchanged zeolite additive
(International Journal of Materials Research, 2006)
This paper deals with the densification and phase transformation of Si3N4 with additives of Li-exchanged zeolite during pressureless sintering at significantly reduced temperatures. Dilatometric shrinkage data show that ...
Synthesis and characterization of Al, Y, Co and Cr substituted ultrafine powder of NiFe2O4
(Materials Science Forum, 2004)
The ultrafine spinel NiFe1.9M0.1O4 powders (M=Al, Y, Cr, Fe) were synthesized by thermal decomposition of appropriate mixtures of complex compounds with acetylacetone - (2,4 pentadione) ligands ([M(AA)(x)]) at 500 degreesC. ...
Hydrogen storage properties of MgH(2)-diatomite composites obtained by high-energy ball milling
(Journal of Microscopy, Oxford, 2008)
To investigate the effects of specific porous microstructure of diatomite on the hydrogen storage properties of MgH(2), a two-step preparation was carried out. The first step was decrepitation of MgH(2) particle size during ...
Role of organic additives in hydriding properties of Mg-C nanocomposites
(Materials Science Forum, 2005)
The hydrogen storage performances of Mg-C nanocomposites have been studied on materials synthesized by ball milling with and without addition of an organic additive. The main purpose of this work is to study in more detail ...
Microstructure and hydrogen desorption in nanostructured MgH2-Fe
(Materials Science Forum, 2004)
Mg-based nanostructured hydrides have been synthesized by ball milling using two alternative approaches. The first is based on the reactive milling of Mg powders in H-2 atmosphere, while the second on the milling of ...
Desorption behaviour in nanostructured MgH2-CO
(Materials Science Forum, 2006)
The influence of the Co addition and synthesis route on desorption properties of MgH2 were investigated. Ball milling of MgH2-Co blends was performed under Ar using different milling intensities and different weight ratios. ...
