“…[ 34–36 ] Generally, the analysis of strength for the composites is related to the interaction between dislocations and hard particles. [ 37,38 ] In this work, TiC and intermetallic Ti 2 Co particles formed in the composites. Consequently, it can be considered that the TMCs exhibited a superior strength due to the strengthening effect of the TiC particles and intermetallic Ti 2 Co compounds.…”

In this work, the microstructure and mechanical properties of titanium matrix composites were tuned by introducing graphene and alloying elements. The titanium matrix composites reinforced by graphene oxide (GO) and cobalt elements (GO@ Co/TA1) are synthesized by the spark plasma sintering (SPS) technique. Results show that the precipitated Ti2Co phase is almost reticulate distributed in the tissue, while the in situ TiC particles are discontinuously distributed at the grain boundaries. The ultimate tensile strength and yield strength of GO@ Co/TA1 composites are 160% and 126% higher than those of pure TA1, respectively. In addition, composites show excellent ductility where the elongation of GO@Co/TA1 is around 10.95%. Therefore, such enhanced mechanical properties can be attributed to the synergistic strengthening effect of interfacial‐distributed TiC particles and intragranular‐distributed intermetallic compounds (Ti2Co), which would provide a new idea for the design of metal matrix composite.

“…In fact, there are plenty of bonding theories about the interface formation and bonding mechanisms of stainless steel clad plates, such as mechanical occlusal effect, metal bond theory, energy theory, diffusion theory, dislocation theory, film theory, recrystallization theory, bay theory, and three stages theory . The interface formation processes of clad plates fabricated by vacuum hot rolling under different rolling reduction ratios and vacuum degrees have been discussed in detail in the previous work .…”

Series of 316L/Q235 stainless steel clad plates are successfully fabricated by hot rolling with different interlayers of ferrum (Fe), nickel (Ni), and niobium (Nb) foils. The interface microstructure, interfacial characteristics, shear performance, tensile properties, and fracture morphologies of clad plates are investigated using optical microscope (OM), ultra‐depth microscope, scanning electron microscope (SEM), electron probe microanalysis (EPMA), transmission electron microscope (TEM), and universal testing in detail. It is observed that the addition of Fe interlayer has rare effect on the interface element diffusion. Clad plate with Fe interlayer can only obtain poor tensile and shear properties, which is attributed to severe oxidation at the clad interface. On the contrary, the addition of Ni and Nb interlayers can both effectively inhibit the diffusion behavior of interface carbon element and remarkably reduce interfacial weak areas of carburized and decarburized layers. This is due to that Ni interlayer can sharply slow down the carbon diffusion velocity, and Nb interlayer can suppress interface carbon diffusion by reacting with carbon element and forming niobium carbide phase. After adding Ni or Nb interlayers, stainless steel clad plates can obtain superior interfacial bonding strength, tensile strength, and fracture elongation, eventually achieving the purpose toward strengthening and toughening the interface.

“…Morsi and Patel et al [12][13][14] fabricated a so-called "dual matrix" Ti-TiB composites as shown in Figure 5(a), which contains isolated reinforcement-rich phase and continuous Ti matrix phase, exhibiting superior fracture toughness. Huang et al [2,15,16] fabricated one-scale network hierarchical TiBw/Ti composites and two-scale network hierarchical TiBw + Ti 5 Si 3 /Ti composites as shown in Figure 5(b). The elastic modulus, passion ratio and yield strength reach to the upper limit of Hashin-Shtrikman theory, as well as high oxidation resistance, superior fracture elongation, toughness and tensile strength.…”

Lamination - Theory and Application

Metal matrix composites with multiscale hierarchical structure and laminated structure have been developed to provide a novel route to achieve high strength, toughness and ductility. In this chapter, a lot of scientific research has been carried out in the preparation, processing, properties and application of metal matrix composite. Many toughening mechanisms and fracture behavior of composites with multiscale hierarchical structure and laminated structure are overviewed. It is revealed that elastic property and yield strength of laminated composites follow the "rule of average." However, the estimation of fracture elongation and fracture toughness is complex, which is inconsistent with the "rule of average." The fracture elongation of laminated composites is related to the layer thickness size, interface, gradient structure, strain hardening exponent, strain rate parameter and tunnel crack, which are accompanied with crack deflection, crack blunting, crack bridging, stress redistribution, local stress deformation, interfacial delamination crack and so on. The concept of laminated composites can be extended by applying different combination of individual layer, and provides theoretical as well as experimental fundamentals on strengthening and toughening of metal matrix composites.
