摘要: Abstract Molecular dynamics simulations are employed to investigate material properties of nanocrystalline aluminum and Al/Ni multilayers at low temperature. For this purpose, both single crystal with different grain sizes morphology used as the substrate. The results show that hardness elastic modulus decrease refinement size in layer thickness multilayers, regardless morphology. Furthermore, angle between two adjacent grains, which is directly connected boundary thickness, has a great influence on multilayers. It shown for 4.5 9.5 nm less than 8 nm, multilayer more affected by rather size.
