Little solid ceramic powder is wetted, coated and bonded by liquid polymer. The viscosity of solid-liquid phase is given by[12] ηsl=[ηl(1-ws/φm)]-2(4) where ηl is the viscosity of liquid phase of polymers, ws is the mass fraction of solid phase and φm is a critical volume fraction at which the mixture has the infinite viscosity. 3.2 Optimal laser sintering parameters......
is decreased with the content increment of nano-Al2O3. The hard alumina nanoparticles in the composites need more liquid phase to wet and bind them. But the liquid binder phase is definite...Article ID: 1003-6326(2005)02-0233-05 Fabrication and mechanical properties of WC-Co-Al2O3 nanocomposites by spark plasma sintering SHEN Jun(沈 军), ZHANG Fa-ming(张法明), SUN Jian-fei(孙剑飞......
. On the one hand, the glass viscosity decreases with the increase of sintering temperature, which promotes the viscous flow mass transfer of the glass liquid phase, thereby resulting in a dense... of the glass, which provides a large amount of liquid phase during the sintering process and therefore reduces the viscosity of the parent glass. As a consequence, the diffusion of ions in glass-ceramics......

prepared by mechanical alloying (MA).The powders were mixed with an organic polymer binder, then injected and debinded. After that, the brown compact was consolidated via transient liquid phase sintering at 1480-1500℃ for 3-5min. The mechanical properties and microstructure of the sintered alloy were studied. At same time, the brown compact was consolidated via traditional liquid phase sintering......
