Introduction With the rapid development of micro-electro-mechanical systems and micro-current system, the requirements of the fluid flow and heat transfer performance in the micro-channel is getting higher attention.
The flow velocity of the fluid, the number of flow channel and size of micro-channel can affect the heat transfer characteristics of the heat sink.
Those research results show that the main factors influencing the heat sink’s thermal characteristics are mainly the size of channel structure[3,4,5-9], the roughness of channel[5], and the fluid flow properties in the channel[7].
The size of the channel structure mainly includes the aspect ratio, and the length of channel and the size of inlet and outlet, the fluid flow properties includes laminar flow, turbulent flow, and two-phase flow.
The properties are listed in Table 1.

Crack growth properties (da/dN-KI relation and KISCC) due to SCC were also examined on pre-cracked specimens based on the fracture mechanics [4].
And the crack growth properties obtained by a single large crack can be used to evaluate only the final part of SCC lifetime.
The critical distance between the crack tips for both cracks to coalesce is given by the fracture mechanics concept, for example, by the stress intensity factors of both cracks.
In the condition of uniform tension of constant strain, as the stress intensity factors of cracks may slightly increase or decrease with an increase in crack length, the period of crack growth is more important in the SCC lifetime.
By inputting appropriate data for initiation of micro cracks, condition of crack coalescence and crack growth properties, the present model would predict the SCC behavior and lifetime in power plants.

Introduction Previous research [1, 2, 3] was focused on the study of stun concrete stress-strain properties, influence of main technological factors on strength range in the width of the construction and it was also studied how load capacity of power transmission line conical poles [4] changes given different percentages of nonpresressed and prestressed steel.
Let`s analyze various factors influence on the supports deformability.

Introduction Powder metallurgy is a summation of innovative processes aimed at obtaining advanced materials or improved properties compared to those obtained by conventional methods.
The evaluation of GHG emissions is made through calculus (the product between the consumption of energy and the emission factor).
The properties of the parts depend on the purity of graphite; an amount of under 0.03% of silicon dioxide reduces the diffusion of carbon in iron.
This is why, in order to realize parts with high mechanical properties, it is necessary to have pure graphite; even a low number of foreign particles lead to a decrease in the mechanic resistance of the steel [8].
Properties of parts obtained by the enrichment in carbon of the iron powders by carburizing or by addition of synthetic cementite fall in value in the requirements for sintered steels.

Complex mineral phases and their interactions with its surroundings are responsible for specific material properties.
The disadvantage is reduced accuracy influenced by many factors.
Thermal analysis The thermal analysis term includes all methods, which study the properties of materials depending on heat treatment.
Besides the phase composition of the material, changes in the mechanical, electrical, magnetic, or other properties can be examined in relation to operating temperature [3,4].
The final appearance of the graphic record is affected by heating rate.

The success of modern technology is largely due to the creation and use of metallic materials with the necessary service properties.
For this reason, it is largely responsible for the formation of superalloy properties.
Since morphology of g¢-phase can decisively affect the mechanical properties of superalloy, it was important to study the structure of various superalloys in detail using structural research methods, which, along with studying the phase composition of multicomponent superalloys, allowed to thoroughly investigate the morphology of g¢-phase.
During longer annealing multi-factor change in material structure takes place.
The latest process of phase recrystallization changes the material properties dramatically and reduces its operational capacity.

As is known to all, the main factors which affect steel's using property are the composition and heat process technology.
Inclusions in steels have bad effects on casting and rolling process of the steel, and surface quality, technical property, mechanical property and corrosion resistance, etc.
Fine carbide and nitride precipitations in the steel can stabilize carbon and nitrogen in the steel and improve properties of the steel through precipitation strengthening.
Compared with sample 1, sample 3 in Fig.2(b) with the highest titanium addition has relative finer grain size and a lot of precipitates, and parts of them grow up which will deteriorate the properties of the steel.
That titanium added to the steel reasonably to fine grain size and to produce dispersion distribution precipitates will improve the mechanics properties of the steel.

Introduction Functional nanostructures are gaining interest among scientists because of the unique properties and capabilities of wide application of these structures.
Results It is known that the properties of CNTs depend on the method of their preparation and modification [2, 13].
It is essential for a further development of nanotechnologies to have a clearer understanding of both the properties of the nano-materials and the mechanisms of their interaction with biological objects [1, 2, 4].

From the standpoint of materialogy [2], it responds to the new vector of the development of the materials science and is one of its most important sections – surface materialogy and entropy-ecological materialogy [3], since provides the creation of a surface layer with enhanced properties and, in comparison with other methods of coatings creating on the surfaces of various products, slightly affects the increase in entropy.
Since the surface of various products determines their functional properties (wear, heat, corrosion resistance, etc.), the prediction of these properties is based on the study of the composition, structure and physico-mechanical and chemical properties of its surfaces, not excluding the study of the properties of the base material.
In Russia, studies are conducted of the energy parameters of the ESA process [8], their effects on the dispersion and properties of the modified surface layer [9], to solve the problem of increasing the thickness of coatings [10], research on the creation of new electrode materials for ESA and properties of coatings [11-14], hybrid technology [15].
