Introduction The emergence and development of new materials manufacturing technologies leads to the invention of new ways to control their properties or to improve existing.
The result of these measurements may affect not only the properties of the product, but also the possibility of its further operation.
Tomography gives the most accurate results, but it is also one of the most complex control methods that require consideration of many technological and physical scanning factors.

At nanoscales, due to the increasing ratio of surface/interface area to volume, surface/interface energy plays an important role in the physical and mechanical properties of solids [1, 2].
However, the classical elasticity theory cannot account for the effects of surface energy on the mechanical performances of solids.
The numerical solutions of the dynamic stress concentration factor are graphically illustrated.
The effects of the incident wave frequency and surface elasticity on the dynamic stress concentration factors in the matrix material are analyzed.
For a larger value of s, the surface energy significantly affects the DSCF around the hole.

Ab initio calculation has evolved into a powerful tool that is widely used in condensed matter theory for the calculation of electronic, magnetic, and structural properties.
Our final demand in mechanical properties such as tensile strength, yield strength, Figure 1 The balance between specific tensile yield strength and elongation for commercial alloys [1] and Mg97Zn1Y2 [4].
The misfit strain field allows solute atoms to affect the motion of dislocations.
The atomic size factors for many metallic solid solutions have been determined and are given in tables published by King [14].
The atomic size factors for non-equilibrium supersaturated solid solutions, however, are not generally available.

H.P.Raturi et al.[3] was experimented on HMMCs of aluminum to study the mechanical properties like abrasive wear rate and hardness.
The mechanical properties of obtained cast composite were compared with the extruded composite.
The density is one of the influenced mechanical properties of wear rate.
The machining factors and their respective levels adopted for the present experimental study were depicted in Table 3.
Mechanical and tribological properties of AA7075–TiC metal matrix composites under heat treated (T6) and cast conditions. 

In doing so, amplitude of stress intensity factor vary in the range of 20 – 35 MPaÖm.
This causes the accumulation of structural and mechanical damages in the material, formation of corrosion and mechanical micro-defects that are potential sites of fatigue crack nucleation and growth [2].
In addition, the changing of structure and properties under the operation increases the risk of unpredictable failure, so it is necessary to establish the relationship between the statistical characteristics of the material and the mechanisms of its fracture [3].
Thus, it practically does not affect the mechanism of its propagation.

Secondly, the surface heat treatment effect, arising due to the variation in temperature of materials affecting the cooling rates and constraint levels within the component.
Another aspect that impacts residual stress development is that of material properties of the substrate, heat-affected zone (HAZ) and clad passes.
Thermal residual stresses arise through the weld cladding process hence thermal and mechanical material properties are of particular importance.
Thermal and mechanical properties are inserted into the FE model, experimentally obtained for the representative clad and HAZ materials using specimens harvested from the clad component as shown in Fig. 1.

Cryogenic treatment of cutting tool material has been reported improving properties of the materials, resulting improved performance.
The life of a cutting tool plays an important role and consequently, is a major economy factor.
So, it is always important to improve the properties of material by heat treatment method, which has better control over the range of the properties that a given material has.  
CT results in physical changes, like shrinkage and densification in the cobalt binder, which retained the carbide particles firmly and enhances the tool material properties.
This was due to improvement in properties of tool material after CT, which did not allow to wear out the cutting edge easily.

The chemical compositions and mechanical properties of titanium alloy (TC18) [2] are shown in Table 1 and Table 2 respectively.
However, other properties have conspired to present difficulties when machining titanium alloy (TC18).
Because titanium alloy (TC18) is a new type of alloy (α+β), a lot of researches work on titanium alloy (TC18) focuses on its microstructure and the properties in China.
The paper explains various factors and parameters involved in milling titanium alloy (TC18) with these three kinds of inserts.
