Effect of Chromium Content on Formation of (Mo1-x-Crx) Si2 Nanocomposite Powders via Mechanical Alloying

(Mo1-x-Crx)Si2 composite powders were successfully synthesized by ball milling of Mo, Cr and Si elemental powders. Effects of the Cr content, milling time and annealing temperature were investigated. X-ray diffraction (XRD) was used to characterize the milled and annealed powders. The morphological and microstructural evolutions were studied by scanning electron microscopy (SEM) and transmissio...

Sintering of Fine Oxide Powders: II, Sintering Mechanisms

Conventional and new sintering mechanisms have been porous compacts is well-known in the ceramic literature. However, several reports have been presented recently that investigated using fine powders of CeO2 and Y2O3 of excellent sinterability. We have verified the validity of Herring’s show that particle/grain size can remain essentially constant up to a density of 92%, and such a resistance t...
