Data analysis For data analysis the free available computer program MePASto [2] was used for first tests.
MePASto allows an automated data reduction from Doppler-coincidence spectra supplemented by a post-processing unit for data analysis.
To speed up CDB data processing flow new program called CDBtool was developed.

During the forming process, data regarding strokes and forces are detected by distance and force measurement sensors for each axis.
The geometry of the rolls as well as their rolling direction and path and the pass reduction are shown in Table 1.
The pass reduction Δt is defined as the sheet thickness reduction in the rolling zone.
Considering the machine deflection, the real pass reduction is lower than the ideal one set by the process parameters.
The pass reduction in stroke 1 is ∆{TTP}8710 t = 0.70 mm, the highest one possible without surface fracture.

The collected data was then imported into MATLAB where in-house code was written to view and calculate microstructural parameters from the data.
Data was also collected for six and ten cycles as well as corresponding sized maps oriented along the rolling direction; however, these are not shown here for space reasons.
For comparative purposes equivalent data after ECAE is presented by the curves marked by square data points.
Contrary to the data presented in Fig. 2 the mean boundary spacings are an average of both directions parallel to the previous deformation and normal directions.
Bearing the above in mind, it can be seen from the data in Fig. 2 that the HAB scale of the ARB microstructure is finer than that of the ECAE material, especially in ND.

The compress rate was 0.1s-1; the deformation temperatures were between 900 and 1050°C; the compress reduction was 5% to 20% for each deformation and the gap time between deformations was from 1 to 30 s.
As the static recrystallization started when the softening fraction increased to 0.2, the static recrystallization valume fraction φsrex can be determined by formula (2): φsrex =(φ-0.2)/(1-0.2)=(φ-0.2)/0.8 (2) The load and stroke data of each sample in this experiment was recorded and calculated to maintain the true stress - true strain curve.
Take the example of the condition where the deformation rate is 0.1s-1, the pre-defoamation reduction is 10% and the recrystallization time is 5s, the static recrystallization volume fraction at deformation temperature of 900, 1000 and 1100°C are 36%, 43% and 48% separately.
Take the example of the condition where the deformation temperature is 1100°C, the pre-defoamation reduction is 10% and the recrystallization time is 5s, the static recrystallization volume fraction at deformation rate of 0.1s-1 is only 3.5%, while the static recrystallization volume fraction at deformation rate of 1s-1 , 10s-1 and 30s-1 are up to 7.8%, 48% and 74% separately.
The increase of deformation reduction, deformation rate promote the recrystallization.

Ø/c Reduction Calculation Method - Ø/c Reduction is an option available in the Plaxis 2D program required for calculating a safety factor that defines soil mass stability.
This method involves the successive reduction of the value of shear parameters, tgØ and c, up to soil mass failure.
Stability calculations were performed using the Mohr-Coulomb model, followed by stability analyses carried out according to the Ø/c Reduction calculation method.
Based on the calculations performed, comparisons were drawn between the maximum horizontal and vertical displacement of the soil mass in the case of the plastic calculation according to the Mohr-Coulomb method and in the calculation variant based on shear parameter reduction.

Absence of additional reducing agents in the system during the reduction process suggests HB-PA itself acted as reducer.
The amino groups in HB-PA can potentially provide electron source for the reduction process [8].
X-ray diffraction (XRD) data of gold nanoparticles were collected utilizing Cu Kα X-ray radiation with a voltage of 40kV and a current of 30mA by X’pert pro diffractometer (Philips, Holland).
Results and Discussion The gold nanoparticles were generated in situ in the matrix of HB-PA through the reduction of HAuCl4 by amino groups of the polymers.
Conclusion Gold nanoparticles were obtained in a one-step manner based on the reduction process of HAuCl4 solution with HB-PA.

The electrochromism of vanadium pentoxide xerogel film can be considered as a reversible reduction/oxidation process accompanying the double insertion/extraction of Li+ ions and electrons.
Comparing to the red-ox potentials of individual components, V2O5, the red-ox peaks of (PEO)0.5V2O5·nH2O are much sharper, and the first reduction peak and the second oxidation peak of V2O5·nH2O are gradually disappearing with cycling.
Therefore, the first oxidation peak and the second reduction peak of the (PEO)0.5V2O5·nH2O film probably arise from the V2O5 xerogel and the first reduction peak and the second oxidation peak are the result of a cooperation effect of the polymer and V2O5 xerogel, in which the reduction peaks correspond to the insertion of Li+ ions and electrons when (PEO)0.5V2O5·nH2O films become green or blue.
Fig. 3 shows ex-situ optical transmittance data for (PEO)0.5V2O5·nH2O film in the as-deposited state, and in different intercalated states, which the film was polarized at -0.3, -0.5, -0.7, -1.0, +0.3, +0.5, +0.7 and +1.0 V for 30 s, respectively.
