“…6; therefore, it is considered that formula (1) represents the reaction that occurred during the joining. However, a previous study reported that the reaction occurred on the surface only, and a major amount of SiC and Al remained on both sides of Al 4 C 3 when the temperature in the above reaction was less than 1473 K. 17) The EDS mappings shown in Fig. 2 indicate that the Si peak mainly existed on the surface of the joining area and a strong Al peak occupied the interior of the joining area; therefore, the reaction was not considered to occur completely during this joining method.…”

This paper describes a novel experiment in which alumina was joined using polycarbosilane (PCS) and an aluminum foil. PCS was used to design the surface structure of alumina, and the aluminum foil enabled the formation of an area that included the alumina surface designed using PCS; this area could be joined to ceramic materials. A four-point bending test revealed that the flexural strength of both the silicon carbide (SiC) and the silicon oxide (SiO 2 ) pieces that were obtained from alumina whose surfaces were modified to SiC or SiO 2 increased, compared with the flexural strength of ceramics joined by alternative methods involving the use of organometallic polymers whose compositions are similar to SiC and SiO 2 . Moreover, it was apparent that alumina was formed by the reaction of SiO 2 with aluminum. However, traces of Al and Si remained in the joining area in both the SiC and SiO 2 pieces.

“…This reaction occurred above 973 K. 17) The joining was carried out at 1073 K, and the existence of metal Si in the joining area was confirmed from the XRD spectrum shown in Fig. 6; therefore, it is considered that formula (1) represents the reaction that occurred during the joining.…”

“…However, in accordance with the Al-Si phase diagram, in the temperature range under consideration, silicon can dissolve into the liquid phase even when its content is very low. This will reduce the DG of the reaction to negative values, leading to the formation of Al 4 C 3 [15,17]. Although the fabrication of Al-SiC composites by powder metallurgy should avoid the interfacial chemical reactions at lower temperatures and the formation of Al 4 C 3 should not occur [18,19], TEM observations have indicated the presence of Al 4 C 3 (Fig.…”

A conventional powder metallurgy method (PM) was used to produce Al-SiC and Al4Cu alloy matrix composites with 2.5, 5, 7.5 and 10 wt% of SiC particles. Two different sizes of the reinforcing phase particles were applied to determine their effect on composite microstructure. The sintering process was carried out at 600°C under nitrogen atmosphere, and its consequence was the appearance of aluminium nitrides in composite microstructure acting as an additional strengthening phase. The composites were next re-pressed and re-sintered (2p2s) under the same conditions. The main aim of this article was to examine the microstructure of the SiC reinforced Al and Al4Cu alloy matrix composites. To achieve this goal and characterize the sintered materials, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) techniques were used.

“…In the continuation of previous works by Bermudez [17] and by Iseki et al [18], a model based on stable and metastable phase equibria has been developed for describing the chemical interaction under atmospheric pressure between A1 and S i c at low and medium temperatures [19]. According to this model, an invariant transformation (quasi-peritectic reaction) occurs in the Al-C-Si system at 650 f 3°C.…”

: The fabrication of high perforn~ance metal matrix conlposites reqoires the optinlization of the interfacial bonding, which supposesa strict control of the reactivity and of the wettability between the matrix and the reinforcement, specially for materials produced by casting techniq~ues. In this stop, two methods are described consisting on the one hand, in the surface treatment of carbon fibres by a particular type of CVD and, on the other hand, in modifying the composition of the nlatrix. The two methods can be used either separately or in combination, sucessful tailoring of the interface being the result of thermodynanlic or kinetic effects.
