Introduction The addition of ceramic particles into a metallic matrix is regarded as a possible way, how to improve the mechanical properties of construction materials, e.g. their toughness and fracture resistance, and to reduce their weight at the same time.
In [2], Guo et al reported enhanced dynamic mechanical properties of the 2Y-PSZ/steel; the improvement of the mechanical properties was explained by the martensitic transformation of the metallic matrix in the process of the transformation-induced plasticity (TRIP).
The results published in the literature show clearly that the mechanical properties of such MMCs are affected not only by the mechanical properties of the individual constituents but also by their interaction at the interfaces.
The possible factors influencing the preferred orientation of crystallites in the TRIP steel thin films are the anisotropy of the elastic constants in combination with the residual stress as discussed above, the morphology of the substrates affecting the morphology of the thin films and the interaction between the substrate and the film.
This encourages us to believe that the interface between the TRIP steel and the ZrO2-based ceramics is a quite important factor, which influences the mechanical properties of the composites consisting of TRIP steel and MgO stabilised ZrO2.

The experiment parameters included on-time duty factor, off-time, voltage, frequency, and current, respectively.
However, as machining micro hole by drilling on Inconel 718 is difficult due to its properties.
Experiment parameters affect to machining time, which is individual conditions and characteristic of micro-hole drilled affect to taper hole difference.
It was found that the main parameters used in the experiment are the factors that affect the time it takes to drill.
Which affect the of electrode wear ratio as shown in Figure 4.

Each species requires optimum temperature and treatment duration without affecting its properties.
Also, the heat treatment process can alter the treated wood's cell morphology, which can affect the other properties of wood [18].
In addition, there are significant differences in the mechanical properties, especially bending strength, reduced in thermally modified wood [32].
The moisture content, relative humidity, and environment temperature are the main factors influencing fungi growth on wood.

Introduction Over the past decades, Inconel 718 is increasing its importance as one of the most interesting group of aerospace materials, due to its unique properties such as high strength thermal resistant and high corrosion resistant.
Moreover, produced heat during cutting is the most important factors affecting performance and productivity of metal cutting operations.
In order to investigate the degree of influence of control factors (cutting tool (A), depth of cut (B), cutting speed (C), feed rate (D), frequency (E) and coolant (F)) on flank wear, hardened, surface roughness and cutting force in milling Inconel 718, six factors, each at three levels, are considered.
In Table 3, the most important variables affecting the flank wear are cutting tool (P = 28.6 %) and frequency (P = 27.7 %), and the feed rate (P = 14.4 %) and depth of cut (P = 12.3 %) are also considered as a significant factor.

This technology affects the following factors: - carbon saturation of the carburized layer; - morphology of martensite and the carbon concentration in it; - volume fraction of the redundant carbide phase and its distribution in the cemented layer; - the presence of residual austenite.
All the abovementioned structural factors affect the change of the carburized layer phases in the process of plastic deformation and, consequently, on the fatigue life of gears.
The glow discharge processing allows not only to reduce the endurance duration in some cases and to enhance mechanical properties, but also to achieve the essentially new effects, related to the availability of phase composition and the diffusion layer structure control.
The identical structural condition of steel after the equivalent modes, both gas and ion carburization, provides the identical change of structure and properties during the deformation hardening.
The reduction of carbon concentration in the matrix (with temperature increase) lowers both the density of fastening dislocation points and the degree of their blocking, what should be positively affect the plastic properties of the matrix.

Taguchi design of experiment method was used for determining testing conditions in order to investigate factors which affected to the residual stresses.
The properties of 304 stainless steel is shown in Table 1.
The model uses material properties temperatures at 20°C such as density of 7.9 Kg/dm3, melting temperature 1,450°C and the other properties on the temperature range used in Table 1.
Results showed that all four factors were statistically significant as Figure 3 (on the left) showed that the change in each main four factors affected to the response.

Early studies [1] used empirical reduction factors which modified the endurance limit of the material to evaluate the effects.
This phenomenon can be theoretically explained by a concept called the stress concentration factor [5].
Then the stress concentration factor can be defined as (1) where Kt denotes the stress concentration factor, γ refers to the ratio between spacing and depth of the asperities, which approximately equals to 1, Rz is the 10-point roughness, ρ is the effective profile valley radius of the surface texture.
Based on the concept of stress concentration factor, qualitative explanation has been presented according to the experimental results.

Hence, it was found that the bath concentrations affect the particle size of as-synthesized Co nanoparticles and finally changed the properties of final product.
Consequently, certain mechanical and corrosion properties can be optimized during material processing due to the control of particle size.
Corrosion properties.
The corrosion and mechanical properties were enhanced with the reduction of particle size.
In conclusion, the properties of electrodeposited Co such as corrosion properties and microhardness are strongly affected by the molar concentration of Co.

However, the local heating produced by both FSW and FSP can leave a fusion zone with reduced mechanical properties and a heat-affected zone with tensile residual stresses that can be deleterious to fatigue performance.
FSP was found to increase the fatigue strength of the Ni-Al Bronze by 70% without affecting the corrosion behavior of neutral salt solution.
Casting porosity provides fatigue nucleation sites that can be eliminated, as the overall properties are improved, by FSP.
A tensile test was performed to establish the properties of the as-received NAB material, prior to FSP, is shown in the table below.
