TL;DR: An updated overview of the different manufacturing processes of composite and nanocomposite metal foams is provided.
Abstract: Open-cell and closed-cell metal foams have been reinforced with different kinds of micro- and nano-sized reinforcements to enhance their mechanical properties of the metallic matrix. The idea behind this is that the reinforcement will strengthen the matrix of the cell edges and cell walls and provide high strength and stiffness. This manuscript provides an updated overview of the different manufacturing processes of composite and nanocomposite metal foams.

TL;DR: A class of soft 3D network materials that can offer defect-insensitive, nonlinear mechanical responses closely matched with those of biological tissues is reported, which suggest potential uses in flexible bio-integrated devices.
Abstract: Many biological tissues offer J-shaped stress–strain responses, since their microstructures exhibit a three-dimensional (3D) network construction of curvy filamentary structures that lead to a bending-to-stretching transition of the deformation mode under an external tension. The development of artificial 3D soft materials and device systems that can reproduce the nonlinear, anisotropic mechanical properties of biological tissues remains challenging. Here we report a class of soft 3D network materials that can offer defect-insensitive, nonlinear mechanical responses closely matched with those of biological tissues. This material system exploits a lattice configuration with different 3D topologies, where 3D helical microstructures that connect the lattice nodes serve as building blocks of the network. By tailoring geometries of helical microstructures or lattice topologies, a wide range of desired anisotropic J-shaped stress–strain curves can be achieved. Demonstrative applications of the developed conducting 3D network materials with bio-mimetic mechanical properties suggest potential uses in flexible bio-integrated devices. The development of artificial 3D soft materials and device systems that can reproduce the nonlinear, anisotropic mechanical properties of biological tissues remains challenging. Here, the authors design a class of soft 3D network materials that can offer defect-insensitive, nonlinear mechanical responses closely matched with those of biological tissues.

TL;DR: In this paper, the structural and mechanical properties of low-alloy steel foams were investigated using spacer particles having different amounts and sizes, and the influence of pore size on stress drop ratio was also studied.
Abstract: Steel foams can be used as lightweight and high-functional materials in applications such as transport vehicles, machines and structural parts due to their low cost, high strength, high heat resistance and good weldability. In this paper, low alloy steel foams (Fe–1.75Ni–1.5Cu–0.5Mo–0.6C) having porosities in the range of 47.8–70.9% with different pore sizes were produced by the space holder-water leaching technique in powder metallurgy. The structural and mechanical property variations resulting from the use of spacer particles having different amounts and sizes were investigated. Irregular carbamide particles were used as spacer. The porosity and pore size of steel foams replicated the initial amount and size of the spacer. Visual inspections were performed for the coated spacers having different sizes and amounts with steel powders after the final mixing. The amount and size of spacer determined the coatability of the mixtures. A decrease in pore size improves the strength of the steel foams by sharing the load with more and smaller pores; however, small pores having the highest porosity can impair the strength because no enough metals hold the integrity of the new pore walls. The influence of pore size on stress drop ratio of steel foams was also studied. The stress drop ratio decreased with decreasing porosity of steel foams. In addition, an increase in pore size caused a bigger stress drop ratio. However, the highest stress drop ratio was determined for small pores having the highest porosity due to the interconnection of macropores in the foam structure.
