Advanced composite material: effect of composite SiC on compressive strength and hardness of porous titanium

Research progress on ceramic nanomaterials reinforced aluminum matrix nanocomposites

“…Recently, there is a huge research interests on various nanomaterials reinforced aluminium/alloy matrix nanocomposites. Aluminum has been reinforced with different types of ceramic or carbon based nanomaterials [7,40,[60][61][62][63]. Wang et al [43] described microstructure, tribological and mechanical properties of aluminium matrix nanocomposite which was reinforced with graphene.…”

“…Recently, there is an extensive research thrust for the fabrication of high performance materials for advanced engineering fields [1][2][3][4]. Advanced composite materials are a class of materials with high strength and modulus, lightweight, good ductility and other desired functional properties [5][6][7][8]. In general, composite materials are defined by a materials with at least two phases.…”

Fabrication of Al/SiC composite foams with TiH2 foaming agent by laser melting deposition

“…The Al 3 Ti formed in 1.0 wt% Al/SiC composite foams is 160.4% smaller than pure Al foams. Figures 6(a)-(b) shows that the presence of SiC nanoparticles as a reinforcing phase will cause the matrix material to recrystallize, leading to grain refinement [23].…”

“…Under the external load, the SiC particles and fined Al 3 Ti can pin the dislocations and make the dislocation bend around them, which induces the Orowan strengthening [8]. On the other hand, the difference of thermal expansion coefficients between SiC and Al matrix leads to thermal mismatch plastic strain, thereby releasing dislocation loops to relax the stress [23]. Then the high density-dislocation will strengthen the Al matrix.…”

“…Earlier research suggested that adding ceramic particles such as SiC, MnO 2, and Al 2 O 3 to melt was an excellent manner for increasing the viscosity in the powder metallurgy route [20][21][22]. As well known, SiC has the characteristics of high-temperature stability, high strength, and low thermal expansion coefficient [23]. Therefore, SiC addition could increase the viscosity of the melt to prevent bubbles from escaping and coalescing and enhance the high-temperature resistance.…”
