By simply rotating the samples on each consecutive pass, therefore by changing the shear plane and the shear direction, controlling the microstructure and the texture of processed material is made possible, therefore becoming possible to control its mechanical properties [11].
Such superior mechanical properties are highly desired when manufacturing advanced structural materials.

Recognizing the significant impact of springback on achieving dimensional accuracy in bending processes, researchers have actively explored several factors which affect the springback.
The material properties used were those of SS400 steel, which were identical to the material data used by Vuong et al. [13].
Accurately defining these material properties is essential for obtaining reliable simulation results.
Mechanical properties of SS400.
This suggests that the thickness of the sheet has a noticeable impact on the bending behavior, affecting both the angle and radius after springback.

In previous literatures, the researchers focused on the fabrication methods, polarization affecting factors, noise elimination, direct current (DC) stability and the development of novel metal surface electrodes.
Searle et al [14] compared the properties of Ag/AgCl electrodes made of stainless steel, aluminum and titanium, but the electrode impedance test for a long time is not reported.
Gong et al [6] taking the gel-to-gel connected method to directly measure the impedance properties of electrodes to analyze the impedance-time properties of Ag/AgCl electrodes with different conductive gel.
To sum up, the performance evaluation of impedance properties and stability of Ag/AgCl electrode are lacking in current literature.
In order to investigate the effect of current size on AC impedance properties of electrodes, the stimulating current was set in the range from 0.5~50 mA.

With the important properties, such as transparency, strength,
coefficient of thermal expansion, through the control of the composition, extent of crystallization,
crystal morphology, crystal size and aspect ratio, glass-ceramics exhibit extraordinary interests for
thermal, chemical, biological and dielectric applications.
It has been reported that good mechanical and chemical properties of glass- ceramic materials in the CaO-MgO-SiO2 system have indicated these materials as suitable candidate for use in wear resistant, thermo-mechanical, biomedical and ceramic-coating applications [7-13].
The bulk chemical composition, nucleant added, final phase assemblage and microstructure are the most important factors affecting the technical properties of glass-ceramic materials [7,8,14,15].
Considering the fact that some aspects of structure and crystallization behavior affected by compositional changes in the CaO-MgO-SiO2 system are still unclear, and different crystal types in glass-ceramic materials influence the properties greatly, it has been decided to conduct an investigation on the characterization and crystallization behavior of the above glass system with the changes of CaO/MgO weight ratio using minerals as the major starting materials.
CaO/MgO weight ratio was chosen as a factor to conduct an investigation on the glass structure and cystallization behavior of the mentioned glass system.

The effects of three factors, the welding temperature, the thickness of the intermediate layer Cu foil and the welding pressure, on the stress distribution of the AZ31B/Cu/LY12 joint were studied.
The existence of residual stress directly influences the mechanical properties of welded joint, and even leads to the failure of the joint in the process of cooling or shortly after the cooling.
Therefore, it was an effective way to improve the performance of AZ31B/Cu/LY12 diffusion brazing joints by analyzing the stress of the joints and then find out the factors that affect the stress of the joints.
Since temperature gradient was large in the process of AZ31B / LY12 diffusion brazing welding, the change of material was non-linear, in the definition of material properties, performance parameters at different temperatures were required.

And within the certain value, the impact properties can be improved by adjusting the end desired impedance inertial parameter and the virtual impedance inertial parameter respectively and reasonably.
In noncontact impedance control, the viscosity parameter of the end desired impedance can affect the impact stabilization process, but have little effect on the stability value.
The virtual impedance viscosity parameter is an important influence factor for the stable value and peak value of the impact.
And the stiffness parameters should keep the system at critical or over damping state without weakening mechanical properties of the impact.
However, because of the complicated inside factors and outside interference, the scientific quantitative coordination principle of the parameters hasn’t given out yet.
