The SIMA process affects the microstructure and alters the dendritic structure to globular.
This kind of distribution of intermetallics causes achieving better mechanical properties specially higher resistance against growth of cracks.

The following points were taken into consideration: i) Steady state; ii) No chemical reaction; iii) Gravitational effect was considered; iv) Particle model was adopted; v) The physico-chemical properties are considered constant.
In this case, two correction factors were used: a factor of cross-sectional area, fs, and the surface area factor, ft, defined by: (20) (21) where, Aneis the cross-sectional area of a non-spherical particleand volume V, Ae is the cross-sectional area of a spherical particle and volume V, Se is the superficial area of a spherical particle and volume V, and Sne correspond to the superficial area of a non-spherical particle and volume V.

(1) Random errors are mainly caused by some factors which are difficult to control, such as the fluctuations of measurement value, detection personnel proficiency, sensory errors and changes in external conditions and a series of problems.
Statistical properties are mostly following a normal distribution.
(3) Systematic errors are mainly caused by detection equipment defective, incomplete or not the specified conditions, the experimental theory, using the instruments incomplete or not in accordance with the specified conditions, experimental theory, experimental methods or experimental conditions not meting the requirements, detection personal habits and other factors.
It contains many factors that light brightness, device performance, binocular imaging system mounting structure, camera imaging model, image preprocessing, image positioning and segmentation, stereo matching and 3D reconstruction, detection process and other processes, affect systematic errors [2].
The Impact of Lighting Brightness The light brightness is an important factor to affect obtained image quality in the environment.

Titanium alloys are commonly used for many aerospace and medical applications because of their properties like high strength to weight ratio, corrosion resistance and heat treatment capabilities.
But, due to the factors like low thermal conductivity and chemical reactivity with the cutting tool, it poses a challenge for the machining operations.
This observation can be explained by the fact that progressively increasing dynamic radii of the tool would affect the chip thickness and hence, the cutting forces.
At higher cutting speeds, the frequency of serrations increases (though size decreases) due to a combination of factors: adiabatic shear band formation, temperature rise, and discontinuous chip formation.

For example: which factors impact on surface quality?
How these factors affect the quality of the surface?
Etc., for these problems, in addition to the accumulation of a large number of practice experience, need us to solve them from the source: It is necessary to understand the geometric structure and properties of NURBS curves, as well as the methods of controlling the quality of NURBS curves quality.
The number and distribution of CV points of the curve directly affects the quality of the curve.
We can see from the above experiment that the number and distribution of the CV points directly affects the quality of the curve, using【Rebuild curve】tool can simplify the existing curve.

Due to which the SZ is the main key region for this study, thus the BM has been trimmed to concise size without affecting the thermo-mechanical model.
To improve mechanical properties, it is crucial to choose the ideal TRS. 3.2.
It should be highlighted that grain size, temperature and plastic strain are the only factors used to differentiate these four zones.

Based on this known sensibility, it is expected that joining techniques related to welding processes affect the phase transition, thus the shape memory and related properties.
In particular joining of NiTi shape memory alloys is considered a difficult task, and is an additional factor to be considered when such materials are implemented.

Research on Nitinol, suggests that functional properties can be preserved upon friction welding in unprotected atmosphere [7].
The structural changes related to thermal (and sometimes mechanical) factors may extend to larger surfaces due to the particular low thickness of the shape memory materials.

By the method of numerical simulation the variation law of stress-strain with time and space around borehole of impermeable rock medium, variety law of rock physical properties parameters is studied.
To the boundary of reservoir, the flow pressure decreases very quickly. 1 Introduction There are a large number of pore or fracture.These defect not only change widely the mechanical property of rock mass,but also affect seriously the permeability of rock mass.There is fluid in the pore of rock mass.Seepage field of rock mass is affected widely by the environment,and the change of seepage field affects stress field in turn.So,the coupling between seepage field and stress field forms.As a result,in the processs of oil and gas development,the intercoupling action between seepage field and stress field should be considered.

Significant fluctuation of chemical composition of steel within the required standards leads to a difference in physical-mechanical properties, which has an adverse effect on the reliability of the formation of the desired operating characteristics of machine parts' surfaces during processing [3, 4].
The situation is escalated by the complex nature of the cutting process and the impact of a number of disturbing factors, starting with blanking operations.
Therefore, the operational accounting of the properties of the processed material and the surface layer by tracking the cutting process itself can be a promising direction.
So, according to the classical concepts, the nature of the chip formation process is determined by the temperature-strength tension, which in turn depends on the physical-mechanical properties of the processed material, the facial layer of the machine part and the cutting tool.
Conclusion Thus, the regularities of the cutting process depend to a large extent on the properties of the material being processed and the facial layer.
