By decreasing the blast distance, number of impacted blast-particles under unit peened area would be increased, and larger strain is induced on the peened surface.
Therefore, the reverse transformation around the peened surface is caused by grain refinement and large shear strain due to the shot-peening test.

Figure 2 is the reflectivity of the three curves becomes larger as the wavelength increases, but when the same wavelength, the samples of 40˚C prepared has maximum reflectance ,because when the reaction temperature is 40˚C, the precipitated gum grains in the process, the number of titanium dioxide nucleus crystals is large, small size, and in the most uniform case,the reflectance of titania particles is strongest. 2.3 Effect of calcination temperature on the particle size of nano-TiO2 Figure 3 is the particle size curve of titania powder in different calcined temperature.

For example, the formation of the required grain size of austenite and the separation of niobium and vanadium carbonitrides require strict adherence to temperature and mode of the thickness reduction over the passes [7-22].
From the graph it is following that as the thickness of slabs decreases, with an increase in the number of passes in the rolling stand, the rolling temperature increases, presumably due to the heat released during deformation.

Introduction Ultra High Performance Concrete (UHPC) is ultra-high-grade concrete with a fine-grained macrostructure and high consistency.
This highly advanced and sophisticated material offers a number of interesting applications such as the production of facade panels, which more promotes abroad.

To calculate the Reynolds number is 16800, then the pipe flow is turbulent.
According to the resistance calculation formula: Industrial pipe equivalent rough grain of height, the value of 0.15 mm galvanized steel pipe.

Hardness of the steel decreases gradually with number of temperature cycles around A1 temperature.

Recently, we have developed a number of methods of so-called non-isothermal kinetics (NIK) and designed instruments allowing one to obtain information about reactions of ceramic systems in a wide range of practically important temperatures and rates.
A theory based on ideas about thermally super-activated solid phase reaction diffusion as a limiting stage of gasless SHS could not explain a number of important phenomena.
These research method and devise offer great opportunities for solution of the following important tasks in civil and military industrial sectors: production of fully melted refractory substances (e.g. large-grain TiC used as a highly efficient abrasive), SHS in systems in which ordinary SHS can hardly be accomplished due to their low heat release (Si + C à SiC, etc), SHS-welding of dissimilar, refractory and ceramic materials and SHS of FGMs [2].
Experiments on ETE are performed by using samples 3–5 mm in diameter and 8–15 mm in height pressed from EM powders or rolled from a number of thin films and foils and characterized by high electric conductivity.
The numbers of 16 autonomous electron-optic channels are indicated on the X-axis.

The researchers used a high-frequency solid-state laser with a wavelength of 1.06 μm and continuous radiation of a gas laser on carbon dioxide with a wavelength of 10.6 μm to break the metal bond, remove adhering chips, level the profile, control the protrusion of abrasive grains, and profile circles.
Naming and designation of factors Levels of variation Intervals of variation – 0 + Processing speed [mm/s] 10 15 20 5 Radiation power [W] 40 50 60 10 Let's introduce designations: х1 is processing speed; х2 is radiation power, which are coded factors, varying at two levels; N is number of experiments; j is the number of the experiment (j = 1, 2,…, N); n is the number of repeated measurements in the j-th experiment; y is the response function; is the average value of the response function.
Since the number of factors is small (two), it was decided to conduct a full factorial experiment of type 22, where the number of factors k = 2, the number of levels p = 2, the number of experiments N = 4, and the number of repeated experiments n = 5.
With the same number of parallel experiments for each combination of factor levels, the reproducibility of the process (the absence of significant deviations) is determined by the Cochran criterion.
(7) The value of the Student's coefficient t (P; fE) for the confidence probability P = 0.95 and the number of degrees of freedom fE = N × (n – 1) =16 was taken from [16].

Colony forming unit (cfu/ml) values revealed that the number of viable cells decreased with high concentrations of ZnO-NP whereas minimal inhibition was observed at lower ZnO-NP concentrations.
At higher calcination temperatures, zinc and oxygen defects at grain boundaries causing merging of grains and resulting in increased crystal size and diffraction peak intensity.
