Effect of heat treatment on green machinability of SiAlON compacts
(Elsevier Science Sa, 2014)
SiAlON based ceramics are promising materials for wear applications such as wire extrusion dies, pipe bending rollers, etc. due to their outstanding mechanical properties both at high and low temperatures. To be able to ...
Towards atomic scale engineering of rare-earth-doped SiAlON ceramics through aberration-corrected scanning transmission electron microscopy
(Pergamon-Elsevier Science LTD, 2011)
Direct visualization of rare earths in alpha- and beta-SiAlON unit-cells is performed through Z-contrast imaging technique in an aberration-corrected scanning transmission electron microscope. The preferential occupation ...
A novel approach for preparing electrically conductive alpha/beta SiAlON-TiN composites by spark plasma sintering
(Ceramic Soc Japan-Nippon Seramikkusu Kyokai, 2008)
An effective approach for preparing electrically conductive SiAlON-TiN composites have been developed. Granules of a designed composition of alpha-beta SiAlON were obtained by spray drying and coated with varying amounts ...
The effects of processing on the alpha <-> beta SiAlON transformation during cycling heat treatments
(Elsevier Science Sa, 2008)
Typical alpha/beta-SiAlON starting composition of formula Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38) was densified by two different sintering processes, hot pressing (HP) and gas pressure sintering (GPS), using Nd(2)O(3) as ...
Wear properties of alpha- and alpha/beta-SiAlON ceramics obtained by gas pressure sintering and spark plasma sintering
(Elsevier Sci LTD, 2011)
In this study, alpha- and alpha/beta-SiAlON materials, doped with Y(2)O(3) and Nd(2)O(3), were sintered using two different sintering processes: spark plasma sintering (SPS) and gas pressure sintering (GPS). The wear and ...
Tailoring the properties of spark plasma sintered SiAlON containing graphene nanoplatelets by using different exfoliation and size reduction techniques: Anisotropic mechanical and thermal properties
(Elsevier Sci LTD, 2018)
SiAlON ceramics are intensively used in different areas but still there is a need to improve the mechanical and thermal properties as well as ease of machinability and reduce the weight. In this study, the effect of graphene ...
Cytocompatibility property evaluation of gas pressure sintered SiAlON-SiC composites with L929 fibroblast cells and Saos-2 osteoblast-like cells
(Elsevier Science BV, 2012)
Although the oxide ceramics have widely been investigated for their biocompatibility, non-oxide ceramics, such as SiAlON and SiC are yet to be explored in detail. Lack of understanding of the biocompatibility restricts the ...
Effect of sintering conditions and heat treatment on the properties, microstructure and machining performance of alpha-beta-SiAlON ceramics
(Elsevier Sci LTD, 2012)
The properties of SiAlON ceramics are strongly affected by the composition and structure of the intergranular phase, which are controlled by dopants, sintering conditions and starting silicon nitride (Si3N4) powder ...
Improvement in the Oxidation Resistance of beta-SiAlON Ceramics Produced from Mechanically Milled Powders
(Trans Tech Publications LTD, 2012)
In the present study the oxidation behavior of beta-SiAlON ceramics, which were produced from conventional and high energy mechanical milled powders, was investigated. High energy mechanically milled powders have lower ...
Identification of Ti incorporation into beta-SiAlON crystal structure through transmission electron microscopy techniques
(Elsevier Sci LTD, 2012)
In this paper, we report the transmission electron microscopy (TEM) observations on the incorporation of Ti transition metal element into beta-SiAlON crystal structure in a bulk beta-SiAlON-TiN composite material. Considering ...
