A comparative study of SiAlON ceramics
(Elsevier Sci LTD, 2012)
Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% beta-Si3N4 was used from refractory grade powders (B1) and another purer 98% alpha-Si3N4 (50A) powder was used to prepare the SiAlON ...
Incorporation of the transition metals (Cr and Fe) into beta-SiAlON crystal structure
(Elsevier Sci LTD, 2011)
Outstanding properties for SiAlON ceramics can be obtained by tailoring the microstructure through alpha-SiAlON and beta-SiAlON phase content as well as a type of secondary phases. It is so far well known that while some ...
Wear behaviour of alpha- and alpha/beta-SiAlON ceramics stabilized with Nd2O3 and Y2O3
(Elsevier Sci LTD, 2009)
alpha- and alpha/beta-SiAlON compositions, doped with Y2O3 or Nd2O3, were densified by gas pressure sintering (GPS). The wear and mechanical properties of the materials were investigated and compared to beta-Si3N4 materials. ...
Analytical transmission electron microscopy observations on the stability of TiCN in electrically conductive alpha-beta SiAlON/TiCN composites
(Elsevier Sci LTD, 2014)
Coating of alpha-beta SiAlON granules with TiCN powder led to a continuous 3D electrically conductive network formation. Here, the stability of TiCN grains following gas pressure sintering (GPS) and its effect on the ...
A comparison of sintering techniques using different particle sized beta-SiAlON powders
(Elsevier Sci LTD, 2012)
In the present study sintering behavior and mechanical properties of beta-SiAlON ceramics were investigated using different sintering techniques (gas pressured sintering (GPS), pressureless sintering and spark plasma ...
Effect of SiC addition on the thermal diffusivity of SiAlON ceramics
(Elsevier Sci LTD, 2017)
Despite the fact that thermal conductivity is a crucial parameter for SiAlON ceramics with respect to their suitability in various applications, including high-temperature structural components, wear parts, and cutting ...
An alternative composite approach to tailor the thermoelectric performance in SiAlON and SiC
(Elsevier Sci LTD, 2017)
The thermoelectric properties of SiAlON and SiC based composites prepared by adding TiCN (5 and 10 vol.%) as a particulate or as a segregated three-dimensional network were investigated. Although the volume fraction of the ...
Investigation on the performance of SiAlON ceramic drills on aerospace grade CFRP composites
(Elsevier Science Sa, 2015)
Carbon fiber reinforced polymer (CFRP) composites are widely used in aircraft structure due to their outstanding physical and mechanical properties. Drilling is one of the most critical operation in the handling of CFRP ...
Oxidation behavior of electrically conductive alpha/beta SiAlON composites with segregated network of TiCN
(Elsevier Sci LTD, 2012)
The oxidation behavior of novel electrically conductive alpha/beta SiAlON composites with a continuous network of 2.5-10 vol% TiCN particulates was investigated. Composites, produced by coating spray dried granules with ...
The effect of the wet-milling process on sintering temperature and the amount of additive of SiAlON ceramics
(Elsevier Sci LTD, 2010)
In this study, nano-sized SiAlON powders were produced by wet milling at elevated speeds as a top-to-bottom process. Before the milling process, different milling times and mediums were performed for the determination of ...
