Fracture micromechanisms in overaged 7000 alloy forgings
(Journal of Alloys and Compounds, 2007)
Micromechanisms controlling the fracture damage in 7000 alloy forgings are studied for T73-type heat treatments. Insight into the fracture modes are obtained by varying the microstructural attributes associated with the ...
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 ...
Microstructure, surface properties and hydrating behaviour of Mg-C composites prepared by ball milling with benzene
(International Journal of Hydrogen Energy, 2006)
Mg-graphite composites, suitable for hydrogen storage, have been synthesized by ball milling metallic Mg with different amounts of graphite and benzene. The microstructure and the surface chemical composition have been ...
Microstructural and sliding wear behaviour of a heat-treated zinc-based alloy
(Tribology Letters, 2007)
The effect of heat treatment on microstructure, hardness, tensile properties, fracture mode and wear behaviour during lubricated and dry sliding of the zinc-based alloy with 25 wt.% Al was studied. Microstructural investigation ...
Fabrication of SiC by carbothermal-reduction reactions of mountain leather asbestos
(Journal of Alloys and Compounds, 2008)
Fibrous magnesium silicate (Mg6Si4O10(OH)s: Mountain leather asbestos) of Serbian origin was used as Si precursor for the Synthesis of SiC by carbothermal-reduction process. As a reducing agent, carbon (from various ...
The dependence of cation distribution, microstrain and magnetic susceptibility on particle size in nanocrystalline Gd2O3/Y2O3
(Scripta Materialia, 2007)
A novel synthesis route based on thermal decomposition of yttrium and gadolinium complexes with 2,4-pentanedione ligand has been used to synthesize 5 nn size (Y0.9Gd0.1)(2)O-3 powder. Refinement of occupancy parameters ...
Microstructural characterization and computer simulation of conductivity in Si3N4-TiN composites
(Journal of Alloys and Compounds, 2004)
Si3N4-TiN ceramics sintered with Y2O3 and Y2O3 + Al2O3 as sintering aids and various content of TiN (0-50 wt.%) were investigated regarding their microstructural and electrical properties. Electroconductive composites were ...
Microstructure and mechanical properties of precision cast TiAl turbocharger wheel
(Journal of Materials Processing Technology, 2005)
From a technical perspective, many of the unique properties of TiA1-based alummides making them attractive for high-temperature structural application also assign these alloys a challenge to process into useful products. ...
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 of pure and doped LaMnO3 powders from citrate precursors
(Materials Science Forum, 2007)
In this work pure and doped LMO were prepared using modified Pechini method from lanthanum and manganese citrates. Lanthanum citrate was prepared starting from La2O3, while manganese citrate was prepared from Mn(NO3)(2). ...
