“…Several literatures reported a formation of ternary carbides of Al 2 MgC 2 [14][15][16][17][18][19][20] by using Mg alloys containing a few Al elements. Formation of Al 2 MgC 2 compounds indicates that solid-soluted Al atoms concentrated around the CNTs by the above HT could improve SHE of the a-Mg matrix [12].…”

“…In contrast, some chemical reactivity exists between molten aluminium and B 4 C [53][54][55]; however, reaction phases can be kept to very small quantities by controlling contact time between molten Al and the B 4 C particles [56]. Typical microstructures for the three types of composites are given in Fig.…”

Model composites of pure Al reinforced with 50% ceramic particles are produced by infiltration. The composite fracture energy is measured by J -integral testing. Marked R-curve behaviour is found. The J-R curves exhibit a break in their slope at a well-defined point. This point is shown to denote the onset of macroscopic crack propagation and is used to assess the composite toughness.Toughness reaches values as high as 40 MPa ffiffiffiffi m p . Quantitative metallography and stereoscopic reconstructions of fracture surfaces are used to estimate the local work of fracture in the process zone. The measured (total) fracture energy is about ten times the estimated local fracture energy, for all composites. The main contribution to their total fracture energy is thus from plastic dissipation around the crack-tip; however, the toughness is still dictated by the local fracture energy. This study hence experimentally substantiates the ''valve'' concept in fracture mechanics.

“…The formation of Al 4 C 3 and Mg 17 Al 12 have been confirmed by XRD analysis of the sample of the 2563y composite after ten thermal cycles, as shown in Figure 11, where the peaks of the aforesaid phases have been identified. The previous studies have shown that, in contact with carbon fibers, aluminum may form the stable binary carbide Al 4 C 3 , [9,[26][27][28] or it may cause the formation of stable ternary carbides of the approximate composition Al 4 Mg 2 C 3 [9,29] or Al 2 MgC 2 [9,[30][31][32][33] It has also been reported in earlier studies by Wu and Zhu [34] that the precipitates of Mg 17 Al 12 are formed at the interface in the as-cast condition of Mg-Al alloys reinforced with carbon fibers. During thermal cycling, these reaction products may become stabilized and, hence, lead to stabilization of the thermal expansion after a few thermal cycles.…”

Magnesium alloy-based hybrid composites with carbon-fiber, SiC p , and in-situ Mg 2 Si reinforcements have been prepared by the squeeze-infiltration technique. The results of the studies done on the measurement of the coefficient of thermal expansion after thermal cycling of these composites show that the thermal cycling initially leads to rapid linear expansion of the composite. However, the expansion becomes stabilized after a few cycles, pointing toward formation of the stable interfaces due to the formation of stable precipitates. The model for the growth kinetics of these precipitates at the interface shows a rapid initial growth of the precipitates with the number of thermal cycles, which becomes saturated after a few thermal cycles. The thermal treatment of the composite lowers the coefficient of linear thermal expansion, which can be explained on the basis of further stabilization of the interfaces after the thermal treatment.
