The choice of biomaterial for medical applications is established on mechanical properties.
Analysis of the prosthesis microstructure clarifies the material properties.
For this reason and other design factors, structural testing continues to be mandatory before a product is placed on the market [8].
The mechanical properties and microstructures of titanium alloys are strongly dependent on their processing history and heat treatment.
It is obvious that we need to keep an optimal microstructure regarding corrosion and mechanical properties, which can be controlled through processing parameters and be standardized in the near future.

Compared to quartz, it has higher electromechanical coupling factors(k2) because of its larger piezoelectric coefficients[5].
However, as far as we know, the theoretical studies for mechanical and optical properties of LGS crystal have not been reported yet.
So it has positive meaning to investigate its structural, mechanical, electronic and optical properties.
Fig.4 shows these SAW properties.
The SAW properties including propagation phase velocity, power flow angle, anisotropic factor, electromechanical coupling factor and temperature coefficient of frequency are calculated in an optimal region defined by Euler angle (90o,0o~20o,0o~180o).

However, in order to improve the properties and eliminate material discontinuous, it is necessary to conduct the remelting process.
The paper presents the remelting processes of thermal spraying coatings in relation to technologies, properties and applications.
Introduction In the case of growing competition on the market, the production of coatings with given mechanical properties is an indispensable part of modern production systems.
The coatings obtained in this way are characterized by specific mechanical properties and adhesion.
These are generally mechanical properties, such as lower strength and modulus, higher strain tolerance, and lower thermal and electrical conductivity.

Research Approach There are many factors to affect the strength of cement soil.
The mainly factors are as follows: (1) Cement: the type, mix proportion and mixing content of cement; (2) Soil property: the property of soil in different area is difference, and even for the soil of different type in the same area, there is also relatively large difference; (3) Degree of mixing uniformity: It is the degree of mixing uniformity of cement.
These factors will affect the strength of cement soil.
Therefore, the tests were done regarding several main influential factors.
Table 1 is the main physical mechanical properties of the soil samples.

The development of thin ceramic shell mould in investment casting process is very crucial as this mould inherited brittle property and highly exposed to the cracking mechanism.
The strength and integrity of the mould are very important factors in ensuring that the metal part has the proper dimensions.

Factors that can lead to instability of desulfurizer includes: (1) internal texture changes and irreversible changes of desulfurizer caused by sintering in the process of desulfurization/ regeneration recycle; (2) loss of active components; (3) stable sulfates produced during regeneration; (4) pulverizing problem of desulfurizer in desulfurization process.
However, the sorbent texture is one of the main factors that affect diffusion.
For desulfurization reaction, pore volume size of desulfurizer is an important factor that affects the desulfurization performance.
He also pointed that pore size, pore structure and crystal lattice defects caused by impurities or additives are the main factors that affect the sulfurization capability of sorbent.
Relationship between fractal dimension and porosity and average pore size Conclusion Besides the active component, the texture property of desulfurization sorbent is also a dominant factor that determines the desulfurization performance of sorbent.
