The number of tests was 30 times, and to report the average value of the measured microhardness.
Adding appropriate content of CNTs can improve the degree of melting of powders, the internal defects of coatings reduces with the increasing melting flow ability of the powders, grain growth is suppressed by CNTs during crystallization.
Fewer defects and finer grains lead to higher microhardness of the coatings [14].

The two PCBN inserts were marked as PCBN 169T and PCBN 169S (equivalent to 1 and 2 µm average grain size of original cubic boron nitride).
At 160 m/min, for PCBN 169S and PCBN 169T, the CBN grains can be broken along the cleavage plane in a severe wear process and then produce cleavage wear.

However, as the number of the domains become large, this model will complicate the relationships among the domains, and may also result in huge cost even through a tiny change on topology structure or role configuration.
The main difficulty caused by this is how to achieve fine-grained authorizations as well as dynamic access control decisions.
The model can flexibly express the fine-grained authorization strategy by combining these attributes and limiting their value ranges.

The course-grained heat-affected zone (CGHAZ) shows basically less softening than the inter-critical heat-affected zone (ICHAZ), the sub-critical heat-affected zone (SCHAZ) also softens a little bit in case of high strength categories, e.g., S1300 base material [8].
Additionally, grain coarsening also happens in this subzone, which reduces strength.
The number of tests were determined by the size of the HAZ, 480 measuring were performed per specimen.

This limitation can be usually overcome by increasing the number of layers in coatings.
All coatings showed a densed and fine grained structure.
It had different grain sizes in the range of 80-110 nm, which showed that the growth of the island mechanism was dominated in the TiN layer.

The soil samples were air-dried at room temperature, and grounded at 0.074mm3 grain size.

Selenium in soil, grain, human hair and drinking water in relation to esophageal cancer in the Cixian area, Hebei Province, People’s Republic of China[J].

Additional characteristics of that kind of metal forming processes are the good surface quality and a homogeneous grain structure of the formed parts.
Therefore, by using micro laser polishing the functional properties even of grained surfaces can be improved.
The remaining data represents the adherent material, which is quantified via a histogram analysis showing the number of detected pixels for each height increment (Fig. 6).

Austenization at higher temperature leads to formation of retained austenite and grain growth which can reduce the hardness of the final product.
Figure 2. a) Measured temperature by IR camera: numbers 1 to 4 represent isotherms of 630 ◦C, 680 ◦C, 880 ◦C, and 1100 ◦C, b) Temperature field at a node with the distance of 13.8 mm from the laser scanning starting point and c) FE predicted thermal history of that point at laser and tool side.
A higher austenization temperature leads to formation of larger austenite grains during the heating process, which can result in formation of more, soft retained austenite in the martensitic structure.

In practical application, due to land function number of different cities or different development stage of the same city may be different; the information entropy of land use structure is often a lack of comparability.
