The formulation number 4 was selected, because it has lower viscosity facilitated the extrusion of the mixture.
All the technical tests were performed on formulation number 4 exclusively. 4 different temperatures of the extruder were tested: 270 ºC, 275ºC, 280 ºC and 290º.

It is seen from the Fig. 3 (a) that the peak around -7 eV is due to mainly ‘s’ states of Al and the number of DOS at Fermi level N (EF) is 1.42 States/eV (Table 1).
One of the standard methods is to calculate the Debye temperature from elastic constants data, since θD may be estimated from the average sound velocity vm by the following equation [24, 25]: (2) where h is Plank’s constant, kB is Boltzmann’s constant, Va is the atomic volume, n is the number of atoms per formula unit and vm is average sound velocity.

General welding (Fig. 2 [a]) is carried out automatically, where diameters of external and internal tracks and total number of passes are 763mm, 753mm and 82, respectively.
Repair welding (Fig. 2 [b]) is applied automatically up to 30mm depth from base metal surface, where treatment width and total number of passes are 13.2mm and 70, respectively.
Even though CAWH and CRWH after PWHT are a little bit different in grain size, there are not much differences in morphologic construction.

To date, a number of effective types of surfactants have been identified as modifying admixtures for concretes and mortars based on traditional portland cements [25, 26].

The choice of graphite as an electrode material is justified by a number of its advantages: - when interacting with titanium forms carbides with high wear resistance; - inclusions of graphite increase antifriction properties, since graphite in a free state is a solid lubricant; - no inert or reducing environment is required, doping may occur in the open air; - when doping with graphite electrodes, the dimensions of the parts practically do not change, which is an important advantage.
In most cases, the sequence of formation of zones, their number, structure and properties depend on the processing conditions discussed above.
The zone of plastic deformation is characterized by the grinding of grains, the formation of large dislocations, as well as the change in lattice parameters.

Additionally, the samples were polished with a diamond solution with ¼ µm grain size to reduce contamination on the growth front introduced by the merging process.
In order to grow thick 3C-SiC material and to study the impact of the necessary supersaturation that keeps the cubic polytype stable, we have carried out a number of growth experiments and simulations in which the source-to-seed distance was varied between 0.75 mm, 2 mm and 3 mm, respectively.

In the continuous distribution area of mobile sand dunes in the hinterland of Taklimakan Desert, pure Aeolian sand is adopted at the upper part of the mobile sand dunes with a height of about 15m in the composite longitudinal sand ridges, with the number a (geographic coordinates of the sampling point: N39º17'26.2 ",E83º46'29.4").
On the edge of the desert where mobile dunes are scattered or partially distributed in patches, in the now dried-up ancient river course and in the woodland where Populus euphratica is sparsely growing, silty extremely fine sand due to river siltation (called silty soil in some literatures) is adopted and separated by sieving. only the part less than ＜0.075mm is used in the test, and the number is z (geographic coordinates of sampling point: N40º49'06.1",E84º17'48.2").
It can be seen that: 1) The relative positions and changing trends of the Surface vibration compaction curve and the Heavy compaction curve are quite consistent, mainly shown in: ①When the content of the Powder clay is less, such as 16.3%, 20%, 25%, 30%, 35%, the gradation of the sample is improved with the increase of the content of the Powder clay, and the increased powder clay is mainly filled in the pores between the sand grains, so that the compaction density is obviously improved on the whole ...

The first 10 samples (numbered in table 1-10) were made with the spot time as variable - the energy (current and voltage) remaining constant (Is = 125 A, Ua = 19.1 V) - and the following 10 (numbered from 11 at 20) the energy (intensity and voltage) changed - the spot time been kept constant, tp = 0.8 s.
Microscopic images of metallographic analysis of welded spots (x100) During the microscopic analysis of the samples in the characteristic areas, a homogeneous structure was noted, with the presence in majority of a dendritic casting structure with possible traces of eutectic at the grain boundary, specific to aluminum alloys.
