At such temperature, coarse austenitic grain is formed that causes increased values of ultimate tensile strength and low value of yield point with decrease to some extend of plasticity indexes (relative elongation and reduction of area), and also low ratio of yield point to ultimate tensile strength of metal.
Results of comparison of the data received by mathematical simulation with results of physical simulation shows adequacy of the model.

Introduction As a substrate materials with silicone rubber, the silicone foam has many advantages, for example, large compressible volume, low-density, good selective permeability, noise reduction, anti-aging, wide operating temperature range, etc, and is an ideal cushion material applied widely in the military and high-tech fields, such as the supporting parts or the buffer sections of the structural components [1-5].
As Table 1 shows that the experiment specimens penetration thickness (d’) of Process B and C have the similar data, but the experiment specimens penetration thickness (d’) of Process A is twice as that of the average value of Process B and C.

The mean from the multiple EDAX composition data, the weight of the alloy layer and the assumption of six and two electrons in the reduction of the Mo and Ni ions allow the calculation of the current efficiency.

The data for density and molar ume measurement for all glasses were shown in Table 1 where the density and molar ume increased from 4.29 g.cm-3 to 5.85 g.cm-3 and 33.05 cm3.mol-1 to 36.95 cm3.mol-1 respectively.
The large magnitude of negative charges on NBOs may rise up the top of valence band and resulting in reduction of the optical band ga The decreasing value of Eopt about 7-12% after irradiation is due to the increase in the degree of network disorder.

The infrared spectra of methylated cardanol (Fig. 4) exhibited reduction intensity of hydroxyl group (–OH) in the range of 3400 cm–1 and increased characteristic absorption of C–O–C linkage of the ether group in the range of 1081 cm–1 compared to cardanol.
GCMS Chromatogram of methyl cardanol by using DMC Fig. 7. 1H-NMR spectra of methylation of cardanol using DMC Analysis of the 1H-NMR spectral data of the cardanol methylation reaction product showed that there were 8 chemical shift regions.

Increasing the angle further to 4.5 deg generated a noticeable increase in forge force in addition to excessive flash on the retreating side and a decrease in weld quality approximately an 8% reduction in ultimate tensile strength and 45% decrease in elongation.
The temperature generated in the weld was recorded in a data logger with a sampling interval of 10 ms and accuracy of ±2°C for a calibrated K-type thermocouple.

The EBSD data were analysed using HKL Channel 5 software developed by Oxford Instruments, UK.
However, due to a reduction of the carbon content of the alloy under investigation and increase of the boron content cavity nucleation sites could be coarse grain boundary M3B2 boride instead of M23C6.

The Energy-Dispersive X-ray Spectroscopy (EDS) analysis data of amorphous SiO2 is shown in Fig. 4.
This results in also a reduction in the rubber matrix to strengthening the biosilica alloy.

These data indicate that the thylakoid membranes can lead to a series of changes at all levels of the plant (cellular, leaf and whole organism), and a delay in flowering and senescence[22].
The final developmental stage of chloroplasts – gerontoplasts – shows an increase in the number and diameter of plastoglobuli, a reduction of the thylakoid system, a loosening of the stacking of thylakoids and a swelling of intrathylakoid spaces[2].

In particular, when a lot of organic composite materials such as carbon fiber reinforced plastics (CFRP) are applied to aircraft components to decrease the weight reduction [3], titanium materials are also used because their thermal coefficient of expansion is similar to that of CFRP and titanium is not subject to damage by galvanic corrosion in contact with CFRP materials.
The above extruded bars of titanium composites were evaluated on an equivalent weight (i.e. areal density (AD)) basis and compared to conventionally rolled thin Ti-64 plate data [7].
