The Q factor can be extracted from hamonic spectra after modal analysis, and the amplitude of Q factor was about 105.
Another important parameter is the Q value of the resonator [3], which affects the stability and use of the device.
Q factor.
This means that the performance of the device depends almost exclusively on the vibration structure, and mechanical properties such as microstructure geometry, material properties, etc.
In fact, the accuracy of the Q value thus obtained is greatly affected by the frequency interval in the harmonic response analysis.

However, the addition of nanoparticle in the MMC to improve its mechanical properties is not unconditional.
To achieve positive gain by adding nanoparticles in the MMCs, all the influencing factors should be taken into consideration.
There are number of factors controlling this issue as discussed hereafter: Critical size of nanoparticles.
Effect of nanoparticles on physical and mechanical properties of MMC Microstructure.
Failure mechanisms It is well-known that mechanical properties of the particle reinforced MMCs are strongly affected by local events such as voids nucleation at the reinforcement/matrix interface, fracture of the reinforcement, initiation and propagation of matrix shear slip bands and the linkage of these local damage and interfacial de-cohesion [9].

The results showed that the surface roughness strongly affected the properties of the superplastically carburized duplex stainless steel while its effects on the non-superplastic material were not that obvious.
Introduction Carburizing is a surface treatment process, to improve surface properties of engineering components.
From this study, we can conclude that the effect of initial surface roughness is important to carburizing properties.
The combination of the two factors eventually leads to better carburizing properties.
The surface roughness of superplastic DSS affects the surface properties of the superplastically carburized specimen where smoother surfaces increased carbide layer thickness and surface hardness.

HEAT TREATMENT IS BY AND LARGE USED FOR ENHANCING PROPERTIES OF THE TOOL STEELS.
The technique of cryogenic treatment is an inexpensive method that improves the physical and mechanical properties of tools.
Cryogenic treatment is the process of cooling a material to extremely low temperatures to generate enhanced mechanical and physical properties.
They studied mechanical properties, wear behavior and microstructure of AISI M2.
In this investigation, which is carried out for 3 factors each factor at 3 levels, an L9 (34) orthogonal array is chosen for conducting the experiments.

The main parameters that can affect the load bearing of the non-flat joints are wave heights, wave lengths and also mechanical properties of adhesives and adherends.
The mechanical properties of the adhesive and adherends are given in Table 1.
The mechanical properties of the adherends and adhesive base.

Reference [6] has reported the column end support condition, column geometry specifically cross-sectional dimensions and also the length, post-buckling behaviour and ultimate strength could be affected the instability phenomena.
A CFS section in compression action is classified a complex of failure mechanics and influenced by a many factors to achieve the ultimate load condition [7].

The double intermediate stiffeners and lipped of the CFS channel was not affected the global buckling of the column, but they can cater the local buckling circumstances in the early stage of applied load.
The comparison is to determine the relationship with another factor such as yield strength, support condition and another dimension of CFS.

Such a material has its own properties that differ from the properties of its components.
In terms of density, i.e. according to the type of pressing, the boards differ in physical and mechanical properties.
As a result, it acquires new properties such as resistance to mechanical and temperature influences.
It is considered to be one of the most sensitive methods that depicts or describes individual mechanical properties of materials.

All these factors results in properties like high tensile strength, strain compatibility, better stress transfer and high impact strength.
Table 2 indicates the experimental factors and their levels.
Mechanical properties of the composite were determined as per ASTM standards and the results were investigated.
It could also be observed that better mechanical properties were due to good fiber-matrix interfacial bonding.

Sintering temperature is the most important factor, which affects on the microstructure evolvement [8].
However, in this study, the phase composition predominantly affects the magnetic properties of NdFeB magnet.
The SPS fabrication temperature significantly affects the structure and magnetic properties of NdFeB magnets as the decomposition of the NdFeB phase was likely to occur at elevated temperature of 950oC and 1030oC.
