Phase studies of reactive infiltrated boron carbide-aluminium composites by quantitative XRD
(Trans Tech Publications LTD, 2002)
Fully dense (> 98 % of theoretical) boron carbide (B4C)-aluminium (Al) composites were produced between 985 degrees and 1370 degreesC by pressureless melt infiltration of Al alloys into porous B4C compacts under an argon ...
Mechanical properties of melt infiltrated boron carbide-aluminium composites
(Trans Tech Publications LTD, 2002)
Boron carbide (B4C)-aluminium (Al) composites were produced by melt infiltration of 2024-T3 series Al alloys into porous B4C compacts in the temperature range of 985 degrees -1370 degreesC under an inert atmosphere (Ar). ...
Transmission electron microscopy of SrO containing multi-cation doped alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2002)
An advantage of alpha-SiAlON is that it can accommodate cations of sintering additives and hence reduces the amount of deleterious remnant intergranular amorphous phase. However, it is believed that relatively large cations ...
Transmission electron microscopy of SrO containing multi-cation doped ?-SiAlON ceramics
(2002)
An advantage of ?-SiAlON is that it can accommodate cations of sintering additives and hence reduces the amount of deleterious remnant intergranular amorphous phase. However, it is believed that relatively large cations ...
Microstructural characterisation of melt infiltrated boron carbide-aluminium composites
(IOP Publishing LTD, 2001)
The microstructure of boron carbide (B4C) - aluminium (Al) composites produced by reactive infiltration were characterised using a scanning electron microscope (SEM) and a transmission electron microscope (TEM) both attached ...
Transmission electron microscopy studies of La2O3-doped alpha-SiAlON ceramics
(IOP Publishing LTD, 1999)
alpha-SiAlON is able to accommodate cations into its crystal structure if the cations are sufficiently small in size, thus helping to reduce the volume of the remnant grain boundary phase after processing. In this study, ...
Novel SiAlON ceramics for cutting tool applications
(Trans Tech Publications LTD, 2003)
New alpha-beta SiAlON ceramics were produced in aqueous medium by Using Multiple oxides as densifying additives. The sintered materials were characterised using a combinations of techniques such as XRD, SEM and TEM. The ...
Performance of new alpha-beta SiAlONs in turning operations
(Trans Tech Publications LTD, 2002)
New alpha-beta SiAlON ceramics were produced, characterised and tested in turning operations of cast iron. Cutting speeds varied between 400-1200 m/min while feeding rates were between 0.3 to 0.5 mm/rev. The results were ...
Performance of new ?-ß SiAlONs in turning operations
(2001)
New ?-ß SiAlON ceramics were produced, characterised and tested in turning operations of cast iron. Cutting speeds varied between 400-1200 m/min while feeding rates were between 0.3 to 0.5 mm/rev. The results were compared ...
