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 ...
The effects of processing on the alpha <-> beta SiAlON transformation during cycling heat treatments
(Elsevier Science Sa, 2008)
Typical alpha/beta-SiAlON starting composition of formula Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38) was densified by two different sintering processes, hot pressing (HP) and gas pressure sintering (GPS), using Nd(2)O(3) as ...
Characterization of Ni-W solid solution alloy powders and sintered compacts synthesized via mechanically activated hydrogen reduction of NiO-WO3 mixtures
(2013)
Blended nickel oxide - tungsten oxide powders corresponding to the compositions of 70 wt% nickel - 30 wt% tungsten were mechanically alloyed (MA'd) for different durations such as 0 h, 6 h, 12 h and 24 h and reduced/alloyed ...

Investigation of parameters affecting grain growth of sintered magnesite refractories
(Elsevier Sci LTD, 2005)
The parameters influencing grain size of sintered magnesite such as temperature (1700 and 1800degreesC), time (19 and 50 min), cooling rate (5, 10 and 25degreesC min(-1)) and various particle size (-3; +3,-5; +5,-8; +8,-10 ...
