Furthermore, the presence of Bi results in a reduction of ductility and in an effective refinement of eutectic silicon when the amount exceeds 0.2 wt.% in a near-eutectic Al alloy [4,5].
The experimental data were processed to provide yield stress (YS, actually 0.2 % proof stress), ultimate tensile strength (UTS) and elongation to fracture (sf).
The reduction of the oxide film formation was not observed in this work.

In cases of evident leakage, the reduction of its volume fraction exceeded 3%.
The measurement of the heat that could be stored/released by the PCA, is an important parameter for the selection of materials for thermal storage. the data was derived by conventional peak analysis in DSC curves.
In as-compacted and after sintering conditions there are only small differences between I and II DSC cycles, even in cases where macroscopic leakage occurred and quantitative microanalyses revealed reduction of tin content.

For example, it has been found that, to simulate a channel flow, has to be reduced from 0.2 to 0.065 which results in the reduction of eddy viscosity by almost an order of magnitude [12].
A mesh independency study is then carried out in order to ensure that the solution is independent of the mesh size which is achieved through a further reduction in mesh size until a small difference in the drag coefficient between two successive mesh refinements is reached.
Results A quasi-stationary flow field solution is needed to be established before extracting the noise data.

Yeob Lee et al. reported the visible-light responsive photocatalytic behavior of NiTi-LDH under a coexisting sacrificial reduction reagent such as AgNO3 [2].
Graphene was obtained successfully by a thermal reduction of graphene oxide in ambient atmosphere at a temperature of 1000 °C for 30 s.
Table 1 shows the parameters of each photovoltage profile, a decay rate of photovoltage kd (sec-1) was calculated by fitting of eq. (1) described below to experimental data by least-square method.

In particular, using Tailored Welded Blanks (TWB), significant advantages can be obtained in terms of weight reduction, fuel consumption and economical and environmental impact.
One of the most effective solutions allowing weight reductions without compromising the integrity of the structure is the use of mixed structures composed by elements in magnesium and aluminium alloys conveniently joined.
Ts and Te, A and D data were chosen in such a way to get the material phase transformation taking into account aluminum and magnesium alloys at the beginning of the numerical simulation and to avoid any transformation back during the process.

Anacardic acids, which are antimicrobial substances employed in the reduction of Ag+ to Ag.
The reduction in thermal conductivity with temperature can be attributed to the fact that temperature altered the original crystal structure of the materials and expose more free electrons and phonons to conduction.

At potentials more negative than - 1.2 V, the junction is blocked, the reduction current being smaller than 20 µA/cm2 at - 2 V.
The reduction current density is smaller than 0.7 A/m2 at - 1 V.
As for as the refractive index of porous silicon (1.3 - 1.6) is lower than that of alumina (1.65 - 1.77), values correlate well with the previously reported data [3], the anodic alumina layer provides an appropriate light guiding effect.

Experimental data of the coated P-91 and linear fit of the logarithm of the deposition rate versus 1/T.
In comparison with the single aluminization, the addition of Zr causes a great reduction of partial pressure of AlCl3 chlorides leads to increase the proportion of AlCl (the principal source of Al in the deposition) and an increase in the deposition rate.Coatings are formed of (Fe,Cr)2Al5 intermetallic phase.
The highest coating thickness is found where 4wt% of Zr in the reactive bed is added and increasing the %wt of Zr causes a reduction of the thickness.
