The analysis of the data obtained with the VERSA 3D microscope (Fig. 2a) has proved the following: an interlayer of white colour is formed at the interface; the interlayer is composed of Fe2Ti and FeTi intermettallics with the hardness of 4.3 to 4.5 GPa.
This is accompanied with a reduction of hardness from 5.2 to 2.8 GPa (at 750°С) and from 3.5 to 2.6 GPa (at 850 °С).

On the early step, the Raman data were compared with the theory based on the Drude model, but more recently the Lindhard−Mermin expression for the dielectric function was used.
The main effect of screening is a reduction of the phonon frequency from LOω to TOω when the number of carriers increases.

In contrast to conventional direct current (dc) electrodeposition, a pulse electrodeposition process was used due to its significant reduction of void formation.
Due to a number of data obtained from EBSD analysis, it is impossible to present all of results and therefore Fig.1 shows, for instance, the orientation image map, the inverse pole figure and the grain size distribution under the current density 0.5A/cm2 and the frequency 340Hz.

Data of shrinkage along the pressure axis, temperature, and electrical power input were automatically stored through a dataacquisition system into a PC.
This can be ascribed to the reduction of particle sizes by ball-milling.

Moreover, the azobenzene substituent with a longer alky spacer attaching to the polythiphens backbone can give rise to a reduction of steric hindrance and consequently oxidation potential for electrochemical polymerization.
The NMR data of the resulting compound is in agreement with its structure.

It was also found out that increment of austempering temperature from 260°C to 390°C resulted in reduction of hardness values due to increment of austenite percentages in the microstructure [12].

The synthesis, performed at temperatures between 1050-1100°C in an open-tube, is based on the carbothermal reduction of silica present as the native oxide on the substrate surface [2].
In agreement with literature data, the emission at 1.73 eV can involve deep levels in 3C-SiC with an activation energy of about 0.5 eV [8-9].

From the figure, we can see that the Cu2+ oxidation-reduction peak high and the half peak wide both increases with increasing the Cu2+ concentration.

There is a high interest in using light-weight foams for automotive, railway and aerospace applications where reduction and improvement in comfort are needed [1, 2].
According to the reference, the theoretical value and data of other researchers are 1.9, 1.79 and 1.2� 4.2[mPa·s] etc., which are smaller than the value obtained in this study.

SOD activity was assayed by measuring the ability of the enzyme in the crude extract to inhibit the photochemical reduction of nitroblue tetrazolium (NBT) by superoxide radicals generated photochemically[8].
All data were subjected to one-way analysis of variance (ANOVA) and LSD multiple comparison test (p<0.05) using the SPSS statistical package.
