Histograms of grain size distributions in Ni after HPT at 80K (a) and annealing at 100 (b); 200 (c); 300 (d) and 400оС, 1 h (e) The deformation temperature affects strongly the thermal stability of the microstructure.
As a rule, fragmentation of structure by various techniques of SPD is accompanied by modification of mechanical properties of materials, particularly, by significant strengthening.
Thus, 3 passes of DCAP result in the microhardness growth by a factor of more than 3.
That is why it is of great importance to study the evolution of structure obtained by various techniques of SPD and variation of mechanical characteristics, particularly of microhardness, at further annealing.

It enables users to visually see the urban street scope, to autonomously roam in the three-dimensional scene and to undertake operations such as query, measurement and flight browsing, so as to understand the direction of future planning and development of enterprises, building districts and even cities as well as to provide visualized geospatial information services for urban construction planning, community services, property management, tourism, transportation, fire safety and so on.
Urban planners can build a wealth of information of a city such as roads, buildings, residential areas and commercial outlets into database and transform into the virtual environment; and then enter the virtual environment through the man-machine dialogue tools and get to know and judge the advantages and disadvantages of various planning programs with different dominant factors through personal observation and experience.
The virtual urban technology includes a comprehensive variety of techniques including: virtual environment modeling, real-time display of complex scenes, mechanical feedback, tactile feedback, human-computer interaction, stereo synthesis, speech recognition and input, and system integration technology.
First, it requires high-precision professional cameras and also has high requirement for the shooting angle, or the generated scenes may be easily distorted and it may affect seamless stitching; besides, shooting light, brightness and shadows should be as consistent as possible, otherwise, after stitching, color may be inconsistent.
Once various instances are created, they will be added to the list of items and all instances can be searched by the name of the index; so when users get the instance’s handle, they can process its properties.

Among the various candidates MOS structures feature with their excellent electrical and mechanical properties of SiO2 and their full compatibility to current Si technology.
These excellent attributes can now be combined with the optical properties of RE.
In this article we will survey our specific approach to Si based photonics, namely REimplanted MOS devices, which combines the excellent properties of MOS structures with the optical properties of RE ions.
Finally the dependence of the EL properties on the anneal temperature should be discussed.
This indicates that with increasing Tb concentration a non-radiative decay path affecting only the 5D3 level becomes more and more intense.

In addition, seawater intrusion is also a major risk factor for causing hypertension when consumed [4].
Another possibility is structural changes and changes in the physical or chemical properties of calcium alginate/GO during prolonged contact with Cl- ions such as changes in surface active sites that reduce adsorption power.
The higher the concentration of CaCl2, the more Ca+ ions will bind to carboxylic groups and oxygen groups that can strengthen the structure of calcium alginate/GO beads and strengthen material properties so as to increase the ability to adsorb Na+ ions.

Pb is known to impact kidney functions, cardiovascular and reproductive health among other things, whereas Hg also affects the brain in addition to the former impacts [28].
The emissions intensity of CFPPs in South Africa far exceeds those of China by a factor of 42.
This has subsequently affected several planned CFPP projects in SADC such as the long-planned 2,800 MW Sengwa CFPP in Zimbabwe (Zimbabwe’s energy policy still favouring coal over renewables, 2020).
Individual countries have to design unique energy transition strategies predicated on multiple techno-socio-economic factors [91,92].
This can destabilise the energy supply and precipitate massive job losses, necessitating huge financial compensation for affected workers, reskilling and redeployment among other necessary interventions [12].

Introduction High-alloy stainless steels enjoy a wide field of application due to their excellent mechanical properties, which are accompanied by adequate corrosion behaviour in the most aggressive environments due to the formation of a dense and stable passive oxide [1-5].
In metastable austenitic steels, a martensitic phase is formed when a mechanical load is applied, which can further improve the mechanical characteristics [6, 7].
As a common factor in most studies, it is stated that the AE signal may, in general, be attributed to the release of gas bubbles due to hydrogen or oxygen formation at the electrode.
For t > 0.75 s, it was assumed that the reduction in the current-time relation was strongly affected by O2 bubble formation and growth.

The quantity and the spacing of rovings in each direction can be independently controlled, thus affecting the mechanical characteristics of the textile and the degree of penetration of the mortar matrix through the mesh openings.
The latter is a measure of the composite action achieved for the mortar-grid structure through mechanical interlock.
This confirms the fact that the shear strengthening scheme selected in this study did not affect the flexural resistance.
Again, the use of polymer coating allowed for the full exploitation of the fibrous reinforcement’s mechanical properties.

TL level therefore is most strongly affected at perihelion.

The WT’s superior time-localization properties stem from the finite support of the analysis wavelet: as b increases, the analysis wavelet transverses the length of the input signal, and a increases or decreases in response to changes in the signal’s local time and frequency content.
Therefore, the WPT have the same frequency bandwidths in each resolution and DWT does not have this property.
The frequency properties for every sub-signal could be very useful to judge the component condition, and thus the FFT is selected to get these kinds of information.
So the changing of the number of hidden layer nodes does not affect the accuracy of the output.

This is because of the advantageous high-temperature and corrosion properties of alloys (in particular, Ti-Al intermetallic compound) are linked to the effect of long-range ordering [1].
Intermetallic compounds based on alloys of the light elements, Ti and Al, are promising candidates for applications as high-temperature engineering materials due to some properties such as low density, high melting point, high strength and creep resistance, high oxidation resistance, low diffusion coefficients etc.
The Ti3Al phase is basic during the creation of industrial titanium materials and provides a beneficial effect for the mechanical properties of Ti-Al based alloys.
Figures 6a and 6b demonstrate how both the concentration and the annealing temperature affect the quantitative and qualitative changes of the kinetic and equilibrium paths.
According to Figs. 7a and 7b, the energy factor has a significant influence on the relaxation kinetics.
