Zhong, “ Effects of grain size and shape on mechanical properties of nanocrystalline copper investigated by molecular dynamics,” Mater. Sci. Eng. A 615, 92– 97 (2014). Web1 day ago · The construction of the model was started with fcc Au with lattice constant of 4.078 Å. The nanocrystalline gold model was then constructed by the Voronoi method [39]. Figure 1 a shows the resulting geometry of nanocrystalline Au film with an averaged grain size of 10 nm. The orientation of grains is random.

WebJan 25, 2024 · Another limitation is the number of cells, which represent the smallest grains. It should be about 4 × 4 × 4 = 64 cells. Then, to calculate the sizes of the cell, the size of the smallest grain should be divided by 3. It gives the sizes of the cell about 24 nm and the sizes of space 12 µm (0.024 × 500), respectively. WebApr 12, 2024 · As shown in Fig. 1 a-b, our composites show a clear laminated structure where graphene layers are aligned at same orientation in copper matrix. Through high-resolution TEM (HRTEM, Fig. 1 c), one can clearly see the ‘sandwiched’ interfacial structure of Gr/Cu submicro-laminates, where ∼2.7 nm thick in-situ grown multilayer … did evan sausage cheat on sssniperwolf
