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 ...
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 ...
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 ...
Influence of beta-Si3N4 particle size and heat treatment on microstructural evolution of alpha:beta-SiAlON ceramics
(Elsevier Sci LTD, 2011)
In the present study, we report the effects of starting beta-Si3N4 particle sizes and post-sintering heat treatment on microstructure evolution and mechanical properties of prepared alpha-beta SiAlON ceramics. Three different ...
