“…The forced CVI (F-CVI) technique was proposed in the mid 1980s [18]. The precursor gas is forced through the bottom surface of the preform under a pressure P 1 , and the exhaust gases are pumped from the opposite face under a pressure P 2 < P 1 .…”

CVI SiC/SiC composites are manufactured via Chemical Vapor Infiltration Process. The SiC-based matrices are deposited from gaseous reactants on to a heated substrate of SiC fiber preforms. An interphase coated on the fibers allows control of damage and mechanical behavior.The advantageous properties of CVI SiC/SiC composites such as their excellent high temperature strength, creep and corrosion resistances, low density, high toughness, resistance to shocks, fatigue and damage, and reliability make them ideal candidates for the replacement of metals and ceramics in many engineering applications involving loads, high temperatures and aggressive environments. Mechanical properties exhibit features that differentiate CVI SiC/SiC composites from monolithic ceramics and glasses, from other ceramic matrix composites and from other composites.

“…In the case of densification by deposition of solid material (e.g., by chemical vapor infiltration), the initially nonoverlapping fibers grow into each other as densification proceeds, and a structure of partially overlapping fibers results. The initial porosities of the fibrous structures that are used for reinforcement of ceramic composites produced by chemical vapor infiltration vary in the relatively broad range [0.4, 0.851 (Caputo et al, 1985;Naslain et al, 1989). At high porosities, the solid phase that belongs to more than one fibers (that is, the overlapping volume) in a structure of randomly overlapping fibers in a small fraction of the total solid phase.…”

Experimental research was performed to evaluate TiB 2-based cathodes, which may be used for retrofitting existing commercial Hall-Herault cells. Candidate cathode materials and retrofit designs were analyzed in laboratoryscale electrolysis tests and nonpolarized immersion tests in molten Al. The cathode materials and cathode attachment designs were selected based on a literature review (Schilling, Hagen, and Hart 1987) and previous experimental research at the Pacific Northwest Laboratory (Hart et al. 1987).
