Thermal expansion of a novel hybrid SiC foam–SiC particles–Al composites

Effect of bentonite addition on fabrication of reticulated porous SiC ceramics for liquid metal infiltration

“…Zhao et al [16] fabricated SiC foam (through the polymer foam replication method) SiC particles-Al composites by squeeze casting technique. They revealed that the SiC foam reinforcement has effective restriction on the thermal expansion of the aluminum matrix.…”

“…They revealed that the SiC foam reinforcement has effective restriction on the thermal expansion of the aluminum matrix. Chae et al [17] produced porous www.elsevier.com/locate/ceramint Available online at www.sciencedirect.com Ceramics International 37 (2011) [15][16][17][18][19] silicon carbide ceramics by using sacrificial polymer microbeads for the fabrication of metal matrix composites.…”

Computational investigation on thermal expansivity behavior of Al 6061–SiC–Gr hybrid metal matrix composites

“…It has been inferred in the experimentation that the reinforcement of Gr with Al-Si and SiC does not enhance the thermal expansivity, thermal conductivity and thermal diffusivity significantly [Okumus et al, 2012]. It has been examined that addition of SiC and Gr reinforcements with high volume fraction results in higher values of thermal capacity, thermal expansivity and thermal conductivity [Okumus et al, 2012;Arockiaswamy et al, 2010;Zhao et al, 2007].…”

“…Al 6061 is the base alloy and reinforcements namely SiC and Gr with different percentage compositions 1.25%, 2.5%, 3.75% and 5% are selected. It has been reported in the literature that the experimental study on Al and SiC has been carried out exhaustively based on low and high weight fractions [Arockiaswamy et al, 2010;Zhao et al, 2007]. But, very limited work has been carried out on the thermal analysis and characterization of Al 6061 with SiC and Gr based on low and high weight fractions of hybrid MMCs.…”

“…For a composite with perfect interfacial bonding between particles and matrix, Kerner's model is suitable for predicting the CTEs of composites. In Turner's model, each component of a composite undergoes a homogeneous strain throughout the composite [Zhao et al, 2007]. In the present research, some of the empirical models considered in the evaluation of thermal expansivity are rule of mixtures, Kerner's model and Schapery's model.…”
