“…Alloying is a good method to improve the engineering properties of pure tungsten metal. As an example, the thermodynamic properties of pure tungsten metal can be improved by alloying with other elements [5][6][7]. The transition metal (TM) elements are selected as substitution solutes.…”

The structural stability, electronic structures, mechanical properties and Debye temperature of W-TM (TM = Cr, Cu, Fe, Mn, Mo and Ni, respectively) alloys have been investigated by first principles method. The lattice constant, cell volume, formation energy and cohesive energy of W-TM alloys are calculated. W-TM alloys still maintain bcc lattice, and have no structural phase transformation. It is shown that W-Mo and W-Mn alloys have better alloying ability with strong interactions between W and Mo/Mn atoms. However, the alloying ability of W-Cu, W-Fe, W-Cr and W-Ni is poor, and there is a weak chemical interaction between W and Cu/Cr/Fe/Ni atoms. Using the optimized lattice, the elastic constants are calculated, and the elastic moduli and other mechanical parameters are derived. Results show that the mechanical strength of W-TM alloys is lower than that of pure W, especially W-Cu and W-Ni alloys. However, the B/G ratio and Poisson’s ratio of W-TM alloys are higher than that of pure W, indicating that TM alloying can significantly improve the ductility of pure W. The metallicity of pure W can be enhanced by doping Fe or Mn, while doping Cr, Cu, Mo and Ni reduces the metallicity of pure W, of which W-Cu alloy has worst metallicity.

“…Fabrication of composite materials is one of the main focuses of up-to-date research. Various composite systems, such as steel/Al [2], steel/Al/Cu [3], Mg/Al/steel [4], and TiTiBw/Ti [5], have already been experimentally manufactured. However, the majority of works has been focused on the Al/Cu clad composite system due to its high thermal and electrical conductivity and low density, as well as the advantage of competitive price in comparison with single Cu materials [1,[6][7][8][9][10][11].…”

“…However, laminated metal matrix composites can effectively delay the strain localization and stress concentration phenomena [26]. Zhang et al [27] reported that the addition of the Al layer can obviously delay the diffuse necking phenomenon of the Cu matrix during the cold rolling process.…”

“…In 2011, Lu et al [28,29] reported that the laminated gradient grain structure based on a coarse copper matrix can be successfully fabricated by surface mechanical grinding treatment (SMGT), which combines the advantages of coarsened and refined nanometer grains, revealing superior tensile strength of 400 MPa and fracture elongation of 60%. Liu et al [26] found that the addition of the TiB w /Ti composite layer effectively delayed the local necking of the Ti layer. The test shows that the fracture elongation of multilayer Ti-TiB w /Ti composite is 20.5%, which is better than the whole Ti (17.5%).…”

Multilayer metal composites have great application prospects in automobiles, ships, aircraft and other manufacturing industries, which reveal their superior strength, toughness, ductility, fatigue lifetime, superplasticity and formability. This paper presents the various mechanical properties, deformation characteristics and strengthening–toughening mechanisms of laminated metal matrix composites during the loading and deformation process, and that super-high mechanical properties can be obtained by adjusting the fabrication process and structure parameters. In the macroscale, the interface bonding status and layer thickness can effectively affect the fracture, impact toughness and tensile fracture elongation of laminated metal matrix composites, and the ductility and toughness cannot be fitting to the rule of mixture (ROM). However, the elastic properties, yield strength and ultimate strength basically follow the rule of mixture. In the microscale, the mechanical properties, deformation characteristics, fracture behavior and toughening mechanisms of laminated composites reveal the obvious size effect.
