Densificaron of Sr-Mg doped SiAlONs with GPS and SPS
(2007)
At temperature above 1200°C, the thermal stability of ?-SiAlON phases has been debated since 1992; however, it has been discussed if any ?-SiAlON phase can be formed in Ce, La, Eu and Sr-doped SiAlON systems. In our previous ...
Carbon nanotube/boehmite-derived alumina ceramics obtained by hydrothermal synthesis and spark plasma sintering (SPS)
(Elsevier Sci LTD, 2010)
Preparation, structure and properties of hydrothermally treated carbon nanotube/boehmite (CNT/gamma-AlOOH) and densification with spark plasma sintering of Al2O3 and CNT/Al2O3 nanocomposites were investigated. Hydrothermal ...
Spark plasma sintering of Co-WC cubic boron nitride composites
(Elsevier Science BV, 2009)
25 vol.% cubic boron nitride (cBN) added tungsten carbide (WC) powders containing 6 wt.% Co (WC-6Co) were densified by spark plasma sintering (SPS) technique under different experimental conditions and the effect of cBN ...
A Novel Approach For Preparing Electrically Conductive SiAlON-TiN Composites by Spark Plasma Sintering
(Trans Tech Publications LTD, 2009)
An effective approach for preparing electrically conductive SiAlON-TiN composites was developed. Granules of a designed composition of alpha-beta SiAlON was obtained by spray drying and coated with varying amounts of TiO(2) ...
Fabrication and microstructural stability of spark plasma sintered Al2O3/Er3Al5O12 eutectic
(Elsevier Sci LTD, 2015)
Al2O3-Er3Al5O12 (BAG) eutectic was prepared by a arc melting process under Ar atmosphere. Button shaped melts, containing fine sized irregular eutectic structures of 'Chinese script', with interpenetrated Al2O3 and EAG ...
Microstructural evolution of mechanically alloyed and spark plasma sintered Ni-W alloy matrix composites
(2013)
Microstructural evolution of Ni(W) solid solution alloys fabricated via mechanical alloying (MA) of Ni - 30 wt.% W powders and spark plasma sintering (SPS) at 1000 C for 3 min were presented in this study. Due to contaminations ...
Interactions Between AlN and SiAlON Ceramics
(Trans Tech Publications LTD, 2009)
In the present study, interactions between AlN and SiAlON laminated couples were investigated after gas pressure (GPS) and spark plasma sintering (SPS) by scanning electron microscopy (SEM) and energy dispersive x-ray ...
Processing, phase evaluation and mechanical properties of MoSi2 doped 4TaC-HfC based UHTCs consolidated by spark plasma sintering
(Elsevier Sci LTD, 2016)
In this research, binary 4TaC-HfC based composites were consolidated using carbide materials and addition of 0-15 vol.% MoSi2 by means of spark plasma sintering at 2000 degrees C. The nearly full dense and monophase specimens ...
