Generally, these materials exhibit superior mechanical properties, such as high strength and good ductility.
This technique can economically produce bulk UFG materials that are 100 % dense, contamination free and large enough for real structural applications.
For the materials subjected to severe plastic deformation, dislocations density () can be given by Eq. 2 [11]: (2) where is the magnitude of Burgers vector and equals to 0.295 nm for Ti [12].

Therefore, Cu-0.6%Al2O3 alloy and Cu-1.0%Al2O3 alloy are the ideal substitution of the traditional electrode materials for resistance welding.
It implies that Cu- Al2O3 alloy can be the best substitution of the traditional electrode materials for resistance welding.

Studies showed that: the material properties of the wall panels significantly impact the self-drilling screw connection property, the carrying capacity of the test specimen are mainly controlled by the bearing strength of self-drilling screw hole side plate.
Investigate the effect of the number of screws, screws space, and screws end space, screws arrangement, plate material and other factors to the connection capacity.
Juanting Chen [25] who was in Southeast University, studied the metal skin structure self-drilling connection performance by introducing material nonlinearity and contract nonlinearity, and gave the generate failure of self-drilling screw equivalent connection and curve of connection.

From the view of engineering application, people were interested in what parameters can not only save materials but also provides the maximum absorption properties of materials in the interested frequency range.
Double cavity structure is composed of two open-cell aluminum foam materials and a mid air-gap and back air-gap.
So in this paper, from the view of save materials, parameters combination 3 is seen as the optimal parameters under double cavity structure.
