SEM examination and XRD analysis showed a fully austenitic microstructure consisting of equiaxed grains in the as received material (hot rolled plates) of both S32654 and S31254 samples, while micro segregation, as a result of processing, was observed in the centre of S31254 samples.

The technique can also be applied to other WBG material with a bandgap above ~2eV such as GaN, AlN, BN and diamond.
According to recent studies, this technique of capacitance determination can be extended to doping measurements on other wide bandgap material such as SiC including multilayer epi structures [6].

From this perspective, those responsible for creation and production evaluate the consequences of processes and materials, looking for alternatives that minimize negative effects as much as possible [14].
The results obtained from the application of the investigation, coupled with the study of the target audience (users), as well as the investigation of the necessary materials, the knowledge of technical and aesthetic details, was possible to advance and reach the final concept of the Product (Fig. 5).

CFG pile means cement fly-ash gravel pile, it is variable strength pile which is made of gravel, stone chips, fly ash, construction waste etc. rejected materials mixed with cement, fine sand and water and which is casted in place by a variety of machines which make pile.
Generally, CFG pile does not need to calculate reinforcement, and can use industrial waste fly ash, slag and stone scraps as admixture materials to reduce the project cost further.
For the main buildings such as matching materials stations, grinding department, cement storeroom, slag powder storeroom workshops etc. which require higher geological bearing capacity we select perfusion pile with post-pressure grouting around pile tip that can have geology bearing capacity changed stronger.

Separate whiskers may appear and grow at 280 o C together with extruded material (Fig.2b), in close vicinity.
Compressive stresses in plastic Cd tend to push up extra material into surface.
As a result Cd occurs under high hydrostatic compression and tends to push up extra material into surface.

The external surface of both electrodes are made of insulating material.
The external surface of the electrodes designed in this paper are made of insulating materials and the signal frequency is in the range of 1MHz~300MHz, so R1 R2 Rs are ignored while in establishing the relationship between sensor output voltage Vo and soil water content θ.
