“…Ma et al concluded that the main crack deflected to the layer interface, and it is interesting to note that crack bifurcation was initiated at the interface between layers 5 and 4, resulting into the stepwise fracture process rather than catastrophic failure as shown in Figure 9. Moreover, it has good ballistic properties that make it popular armor application [21,29]. …”

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.

“…This issue could be illustrated from Figure 3. On the other hand, the fact that the electrode shows better pore inter-connectivity than the supporting layer at a given sintering temperature could also be attributed to more second phase CGO (35%) than YSZ (17%) in the matrix LSM, and therefore the degree of densification retardation in the electrode is stronger [16]. The variations of porosity and average pore size with sintering temperature of the electrochemical reactors are shown in Figure 4.…”

In the present work, 12‐layered electrochemical reactors (comprising five cells) with a novel configuration including supporting layer lanthanum strontium manganate (LSM)‐yttria stabilised zirconia (YSZ), electrode layer LSM‐gadolinia‐doped cerium oxide (CGO) and electrolyte layer CGO were fabricated via the processes of slurry preparation, tape casting and lamination and sintering. The parameters of porosity, pore size, pore size distribution, shrinkage, flow rate of the sintered reactors and the electrical conductivities of the supporting layer and the electrode in the sintered reactors were characterised. The effect of sintering temperature on microstructures and properties of the sintered samples was discussed, and 1,250 °C was determined as the appropriate sintering temperature for reactor production based on the performance requirements for applications. Using the present ceramic processing route, porous, flat and crack‐free electrochemical reactors were successfully achieved. The produced electrochemical reactors have the potential application in the removal of NOx and soot particles emitted from the diesel engines.

“…The incorporation of both metal and ceramic in a graded structure allows the forming of the armor with prefect integration of many desirable properties combining both advantages of metal and ceramic. In our previous work [22], titanium diboride-titanium FGMs were fabricated by stacking and hot pressing for the application of armors. In the present work, alumina and iron, which are most common and abundant materials in ceramics and metals, respectively, were selected, and functionally graded alumina-iron components were fabricated via a simple route of and cost-effective die pressing and pressureless sintering.…”
