The study focused on the effect of alumina content on the physical and mechanical properties of such ceramic foams sintered at 1500°C for different sintering times.
Physical properties and mechanical strengths depended upon ceramic composition as well as sintering time.
Several characteristic properties of porcelain ceramics (e.g. mechanical strength, dielectric strength, corrosion resistance and thermal stability) cannot be obtained in other materials [10].
Instead, pore size and pore distribution after sintering strongly affected the physical and mechanical properties of the porous ceramics.

However, the apparent mechanical properties of the nonwovens are generally rather weak.
Table 1 lists the mechanical properties of electrospun fibrous mats of the polymer blends.
Fig. 6 shows the mechanical properties of the polystyrene fibrous mats treated at different temperatures.
The mechanical properties were dominated by the two factors, the disorientations of fibers and the increase of interfiber adhesion, and the soaring up of the strength could be due to the superfluous solderings among the fibers.

At present, the superheater and reheater pipes in supercritical and ultra-supercritical boilers have encountered with widespread problems of high temperature steam oxidation, seriously affecting the operation safety and economy of the power generation unit.
Factors on the high temperature steam oxidation resistance of metal materials are mainly divided into three categories: the nature of oxide films, internal factors, and external factors, namely the external environment.
Internal factors are inherent properties of the material, and the nature of oxide films plays a role through mainly affecting the transfer and migration of metallic cations and anions.
To a certain degree, these methods improve the anti-oxidation properties of the material to steam, but there still exist some problems.
We put the Super304H specimens into the mechanical centrifugal shot peening equipment, and then adjusted the revolving speed and the pellet flow to an appropriate level.

In addition to this the final product has to have the right level of mechanical properties.
It has been reported [26], using a valve rocker arm as an exemplar, that the level of mechanical properties attainable from both Ti and Ti6Al4V using powder compact forging depends on several factors [26].
Mechanical Properties Although the published work on powder compact forging is scarce, the available evidence confirms that good levels of mechanical properties are achievable [24, 26, 31, 32].
This offers an opportunity for the wider application of Ti-6Al-4V parts with high oxygen content, due to their excellent mechanical properties.

Similarly, we can see that strain rate sensitive factors were decreased with increase in strain.

.% NaCl solution) was investigated, and its tensile mechanical properties were tested before and after corrosion.
The corrosion of reinforcing steel is one of main affecting factors to the duration of concrete structure, which has attracted people’s extensive attention.
There are two important factors to lead to the corrosion of reinforcing steel [1]: one is the carbonization of concrete, and the other is the inrush of chloride.
The self quality of concrete structure is also one of the main factors to cause the corrosion of reinforcing steel.
The tensile mechanical properties, including yield strength, tensile strength and elongation, are tested by a hydraulic pressure universal testing machine.

The factors that affect the fracture toughness of the modifies epoxy such as morphology, particle size and composition are interdependent; hence it is very difficult to study the effect of individual parameter [4].
However, the CB tends to form larger agglomerates and affect the mechanical properties.
Flexural Properties.
This may resulted from higher interaction of CB than epoxy-CB interaction that cause the mobility of epoxy-CB lowers, than affecting in low strength.
