Abstract:We have investigated the influence of the milling time on the structure and mechanical properties of the nanocomposite, as well as the effect of grain size on the sintering kinetics (α to β silicon nitride phase transformation). As we observed, by increasing the milling time the mechanical properties of the ceramics may be improved. The reason of this improvement is partly due to the α-Si3N4 to β-Si3N4 transformation facilitated by the smaller grain size, on the other hand it is due to the better dispersion of… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
