SiC Device Manufacturing: How Processing impacts the material and Device Properties U.
If the cost of the material has an economic impact on the finished product (electronic device), its crystal quality affects the electronic properties of the device.
Epitaxial growth results in the formation of point defects and, in a compound material as SiC, a wide range of intrinsic point defects can be found: C- or Si-related vacancies or interstitials, as well as their complexes can introduce electrically active levels in the band gap, ultimately affecting the electronic properties of the device.
In the following, we will discuss which defects arise during the main processing steps of device manufacturing and how they affect the electronic properties of the devices.
Summary Extended and point defects can severely affect the electronic properties of SiC devices.

For the theoretical study of the rolling process, Forge2011® was employed, which is finite element method-relying software that enables the thermo-mechanical simulation of rolling processes in a triaxial state of strain.
In order to use the results of simulation employing the simplified Archard model for the quantitative evaluation of roll wear, it is necessary to define the factor of wear and the hardness of the tool as a function of temperature.
Introduction The continuous rolling of long products can be ranked among the most efficient processes that enable a long product having high mechanical and strength properties and good quality of the surface to be obtained within a narrow range of dimensional tolerance.
The passes wear during operation, which affects the dimensional accuracy of the finished product and the run of the rolling process [1–3].

During a typical machining operation of such alloys, high cutting forces imposed by a tool on the work-piece material lead to severe deformations in the process zone, along with high stresses, strains and temperatures in the material, eventually affecting the quality of finished work-piece.
Conventional machining (CT) of Ti- and Ni-based alloys is typically characterized by low depths of cuts and relatively low feed rates, thus adversely affecting the material removal rates (MRR) in the machining process.
However, these excellent mechanical properties are generally paired with poor thermal conductivity, high abrasivity and high chemical affinity with common cutting tool materials, thus impairing their machinability [3,4].
Material properties of the alloy are presented in Table 3.

Cho, has presented the dynamic fluctuation of the thermal shock stresses employing practical inertia quantity and material properties through the orthotropic thick cylinder shell made of glass/epoxy, [4].
Thermal loads are affected by the time periods, the diffusivity property of the material, supplied heat flux and the ratio of the inner and outer radii.
In the cooling case, the transient temperatures calculated are of relevance with a period of time as shown in Fig.4.The roles of the convection coefficient of the forced air with the diffusivity property of the material, in addition to the inner and outer radii have a very important implicit effect in the thermal loading results As well as, the effects of the thermal expansion factor and the stiffness property of the material on the thermal stresses.
The combined effects of the time, material properties and the ratio of the inner and outer radii of the hollow cylinder on the transient temperature gradient are clearly domenstrated.Hence; their functions on the thermal stresses must be taken in consideration.
Also, the thermo-elastic stresses are mostly influenced by the thermal expansion factor and stiffness properties of the material.

Studies show that it affects large extent the performance of material when the banded structure serious and uneven distribution.
A lot of plastic inclusions which mostly are sulfide and silicate, long strip of inclusion similar to the tip in tablets, and the distribution chain in the intensive band ferrite, at the same time, the long strip of inclusions reduce the transverse properties of steel dramatically [1].
The distribution of which inclusions and the cracks is about perpendicular is the main reason for crack formation and affect the uniformity of transverse mechanical properties when the steel cold-bend.
A large number of tests and research have proved that [2 ~ 4]: The performance of steel is greatly affected on non-metallic inclusions.
This sulfide accumulation is an important factor causing cracking of steel.

There is a galvanic sediment junkyard in Myjava district, which comes from production of metals and metal products, and has been affected by environmental inappropriate technological applications.
A soil of Gelnica district is burdened by natural resources mining, mechanical engineering and non-ferrous metals metallurgy.
According to our survey results, the districts with a higher degree of agricultural soil contamination with heavy metals are located in different regions of Slovakia, and the degree of contamination depends, among other factors, on the type of soil, mining activities, local industries, traffic, or usage of artificial fertilizers and pesticides.
The overall soil condition is significantly affected not only by current public attitude and approach to this topic, but especially by careless behaviour in the past.
