The main importance is attached to the mechanical (strength, elasticity, deformability, stiffness) and thermal (heat resistance, temperature resistance) properties.
Some number of metals have certain properties, which are almost reached its ceiling, and some cannot be made, in principle (e.g., elasticity and high viscosity, the proper heat resistance and heat resistance in an oxidizing atmosphere and under the influence of mechanical loading and temperature above one thousand degrees, etc.).
They suggest monitoring the properties of the material, heating mode, performing physical and mechanical and other types of analysis, they are carried out before or after heating.
Ambient temperature is a compelling factor in the impact, the internal temperature – the response.
In addition, the properties of the semi-finished product by external feedback of IDS-diagram method are controlled and the anticipated data on the product properties by an external feedback of IDS diagram method are formed.

Significant thermal properties of nanofluids have been improving depends upon fluid-based properties, nanoparticle's thermal conductivity, and the concentration of nanoparticles.
However, the electrical properties of insulation material will change gradually during operation.
Rajab et al. studied the aging properties of PFAE, M182, FR3, and mineral oil.

Introduction Film technology is very important for improving the properties of materials.
It can solve the contradictions among the material properties [1,2].
According to the above-mentioned experiments and simulation of μLSP, the RSM was used to analyze the process parameters (laser power density I, laser spot diameter d and the number of shocking n), the three factors were independent and defined as X1, X2 and X3, respectively.
The 3D response surface figure and contour line analysis figure were fitted, and the influence of each two factors on residual stress in TiN film was investigated, shown as in Figs. 6a-c.
In order to seek the best combination of each factors, the regression equation Eq. 1 was treated by the math methods, and the code of variables (X1, X2, X3) was calculated to be (0.93,-0.11,0) according to the extremum equation.

Interactions between the matrix and the filler particles may be of varying strength, and it has an effect on the rheological and mechanical properties of the composite [1].
The combination of the magnetic properties of the filler and the elastic properties of the polymer matrix in magneto-elastics gives rise to a number of unique properties.
Since the magneto-elastics are composite materials, their mechanical behavior defined by a combination of elastic properties of the polymer matrix and the properties of the magnetic particles distributed within the matrix [3].
The research results ability of the polymer to maintain strength and plastic properties after swelling in aggressive liquids in a relaxed state to change one or more physical and mechanical properties are displayed in Fig. 1.

In the powder metallurgy, even if material was chosen, the carrier mobility and thermal transport property is changed by several factors such as pore, particle boundary and oxide layers.
Thermoelectric properties of the spark plasma sintered samples.
Bi2Te3-based single crystals show anisotropy in thermoelectric properties.
Anisotropy of thermoelectric properties.
Such anisotropy of thermoelectric properties is also confirmed from XRD pattern.

Until now, it has not been solved enough for the thermal properties of the hybrid journal bearing with super-high speed.
Because the heat is generated mainly from the oil film in the bearing, the characters of the temperature field of the oil film are the key factors to investigate the thermal properties of hybrid journal bearing.
As the main object to study, the liquid and its flow direction are the key factors to build the geometric model of the oil film.
(4) Defining the material properties.
Otherwise, the various material properties may also be defined as the functions of temperature considering demands.

These elastic structures interact with the fluid dynamics, affecting recirculation zones and flow separation downstream of the BFS.
By investigating the influence of various parameters, such as the elasticity of the fin, their positioning, and their length, this study seeks to enhance comprehension of how these factors affect fluid flow rates and thermal behavior.
The fluid flowing within the conduit is the air, while the thermophysical properties are listed in Table 1.
Thermophysical properties of air and steel at 20°C [52].
In fact, the maximum displacement occurring just below the top of the fin is attributed to the interplay between fluid dynamics and the mechanical properties of the fin.

The parameters that affect the concrete spall damage are investigated.
Since spall damage, although usually occurs only in a local area close to the explosion, also depends on the structural properties such as flexural toughness, the results of RC slab spall damage might not be applicable to predict RC column spall damage.
The strain rate can be approximately calculated as =220/s; then the dynamic increase factor for concrete tensile strength can be obtained from the strain rate curve [5] , and in this case Dynamic Increase Factor (DIF)=7.
Other column configurations and material properties are hold the same as given in last section.
Dynamic increase factors for concrete.

It was the purpose of the present study to correlate the anisotropic properties of AA 5005 sheets with their crystallographic texture.
The VPSC model is a very versatile polycrystal approach which accounts for anisotropic properties of both the individual crystals and the aggregate as a whole.
The average Taylor factor can then readily be computed by integration over the Taylor factors of the individual orientations that make up the sheet texture.
Stress/strain curves were then obtained by inputting the resultant Taylor factors in Eq. (2).

It uses solidification conditions rather than mechanical or electromagnetic stirring to control nucleation, nuclei survival and grain growth, and then achieve a fine-grained and non-dendritic microstructure for semisolid casting.
Solidification conditions, such as melt superheat, mould preheat temperature, cooling rate and thermal properties of the mould material, are the factors that influence the wall crystal formation, survival and growth, which then affect the final microstructure.
