Processing of B4C Particulate-reinforced Magnesium-matrix Composites by Metal-assisted Melt Infiltration TechniqueYantao Yao,Liqing ChenState Key Laboratory of Rolling and Automation,Northeastern... fabricating composites by metal melt infiltration,a simple and viable method has been proposed in this paper where a small amount of metal powder with higher melting point is added to the ceramic preform......
preform under centrifugal force field were modeled numerically. The results show that the transient solidification and remelting phenomena appear on the infiltration front and can be divided into two distinct regions: the remelting region and solid-liquid congruent melting region. The decrease of porosity always results in the increase of moving velocity difference between the infiltration front......

) (State Key Laboratory of Powder Metallurgy (Central South University), Changsha 410083, China)Abstract:Before densification by chemical vapor infiltration, carbon or SiC nanofibers were grown... infiltration were investigated. The results show that the nanofibers improve the surface activity of the carbon fibers and become active nucleation centers during chemical vapor infiltration. They can induce......

of Technology, Harbin 150001, China)Abstract:Ti-Al complex with a network microstructure was successfully fabricated by pressure infiltration. The fabricated Ti-Al complex was investigated and analyzed by OM, XRD, SEM and EDS. The temperature of pressure infiltration was reduced by using Al-Si eutectic alloy instead of pure Al, which can effectively decrease non-diffusion reaction between liquid Al......
