“…Interfacial reactions and degree of wetting of the reinforcement (fibers) also affect the properties of the composite [8][9][10]. Formation of aluminum carbide (Al 4 C 3 ) has been observed at the interface in liquid metal infiltrated aluminum silicon alloy composites reinforced with carbon fibers containing 7 wt.% [11] and 13 wt.% Si [12]. VidalSetif et al have shown reduction in strength and premature failure of 75 vol.% carbon fiber reinforced A357 alloy due to formation of Al 4 C 3 and presence of brittle Si particles [13].…”

“…There are three reasons for why there was no Al 4 C 3 produced at Gr/Al contact interface: i) the Gr has high crystallization degree, and surface of Gr is smooth which is not conducive to generating Al 4 C 3 , besides, ZL101 was adopted as the matrix material, of which silicon can suppress the generation of Al 4 C 3 ; [23,24] ii) at 750 C, the Al 4 C 3 at the C/ Al interface is often observed in graphite/carbon fiberreinforced aluminum matrix composites, whereas, in this process molten aluminum alloy was infiltrated at 700 C, a low temperature which did not reach the suitable temperature at which Al 4 C 3 would be generated; [25] iii) molten aluminum alloy was infiltrated into graphite prefabricated block in a short time, therefore there was no Al 4 C 3 generated. Table 4 displays the thermal diffusivity perpendicular to the pressing axis and the specific heat capacity of Gr-Al composites with various graphite content.…”

Graphite prefabricated blocks are fabricated using natural flake graphite and pore-forming agent of urea, and then high volume fraction graphite-aluminum (Gr-Al) composites are fabricated applying graphite prefabricated blocks and aluminum alloy (ZL101) by vacuum infiltration process for the electronic packaging materials. The microstructures of graphite prefabricated block and Gr-Al composites are observed in detail, which shows that the graphite maintains a good integrity and arranges uniformly in aluminum alloy. Besides, the result shows the formation of a tightly adhered interface between the side surfaces of the graphite and aluminum alloy matrix, and no detrimental Al 4 C 3 phase is found. Thermal properties of Gr-Al composites are researched perpendicularly to the pressing direction. Thermal conductivity increases from 282 to 398 W mK À1 whereas the volume fraction of flake graphite increases from 40 to 75% in the composites, this reveals that the vacuum infiltration is a very promising method to synthesize Gr-Al composites.

“…This pressure on the cathode would be a decreasing function toward the center of the cell as the effect of the magnetic field decreases with distance. Thus, the cathode surface will have a nonuniform force distribution, which may have a significant impact on the wear of the cathode surface [28,29] and on the mass diffusion (sodium) into the cathode block. [30] Thus, we postulate that the Lorentz force will have a shearing effect on the cathode surface and may have significant influence on various parameters such as aluminum carbide formation and/or sodium diffusion into the cathode block.…”

A mathematical model of magnetohydrodynamic (MHD) effects in an aluminum reduction cell using numerical approximation of a finite element method is presented. In this numerical model, the magnetic field resulting from the cell cathode bus as well as the magnetic field from both downstream and upstream cells are included. The article outlines the three-dimensional simulation of Lorentz force distribution that results from current distribution in both the cathode bus and the cell linings. These forces are important in the side channel of the cell as the current changes its direction because of an inclined sidewall design. Thus, the present work has two main features, which are (1) a numerical model to predict Lorentz field distribution in the electrolytic cell and (2) the influence of sidewall design on current distribution in the side channel and MHD forces. The model predicts that the magnitude of Lorentz force is at its maximum near the sidewall (i.e., along the side channel). The radial component of the Lorentz force creates a concentric rotational flow field, whereas the radial component is responsible for the metal ''heave.'' Results are obtained for different inclination angles (h = 50 to 64 deg) of the sidewall insulation and at different pot-line currents (140 kA to 180 kA). The direction of the resultant Lorentz force is greatly influenced by the slope of the sidewall and is important to the convective flow of metal and bath in the cell.
