Processing and characterisation of three-layer alumina-based composites with enhanced damage tolerance
(Elsevier Sci LTD, 2005)
Three-layer alumina-based composites reinforced with iron in the inner layer and with chromium in the outer layers were fabricated by first uniaxially pressing the three-layer assembly, followed by cold isostatic pressing ...
Pressureless sintering of hexagonal boron nitride powders
(Trans Tech Publications LTD, 2007)
Pressureless sintering of hexagonal boron nitride (BN) with and without additives was performed using a powder which was previously nitrided at 900 degrees C and then heat treated at 1400 degrees C. Sintering additives ...
Spark Plasma Sintering of Silicon Nitride-Boron Carbide Composites
(Trans Tech Publications LTD, 2009)
Si(3)N(4)-B(4)C composites containing fine and coarse B(4)C particles were produced using Al(2)O(3) and Y(2)O(3) as sintering additives via spark plasma sintering (SPS) technique. Phase assemblages of the produced composites ...
Mechanical properties of magnesia-spinel composites
(2002)
A set of dense magnesia-magnesium aluminate spinel composites has been prepared by hot-pressing magnesia powder using 0 to 30 wt.% of spinel powder of mean particle size 3, 11 and 22 µm. Bend stength, modulus, and fracture ...
