There are several effective parameters affects the physical properties of kerosene based magnetic fluid such as consistency of reacted forerunner, molar ratio between reacted forerunner, temperature, pH value and the dropping speed of reacted solution.

The deterioration process in timber is different than the other materials, such as only a change in geometry is observed whereas the mechanical properties are not affected.
The geometric and mechanical properties of timber structures are considered as random variables, as are the loads and the effects of deterioration.
Random variables were used for the definition of the mechanical properties of the materials and the applied loads.
Since this factor influences both the design values for mechanical and resistant properties of timber, its contribution is very important in safety analysis of a timber structure.

High-entropy alloys (HEA), a new generation alloy system offer superior mechanical properties with solid solution strengthening.
Detailed studies on the microstructure, mechanical properties and oxidation and electrochemical properties suggested that AlxCoCrFeNi-HEA be an eminent candidate in structural applications at high temperature, severe corrosive and radiation environments, as the substitute for presently available alloys [5-10].
Generally, welding involves the uncontrolled heating and melting followed by re-solidification which will alter the grain size and chemical composition of HEA weld metal, which can affect welding metallurgy, mechanical and corrosion properties of HEA [19].

According to above mentioned, there is no commercial slurry for chemical mechanical polishing SiC crystal substrate, and also there is no a set of complete chemical mechanical polishing process.
Two surfaces have different the chemical and physical properties, and will have different slurry ingredients.
Polishing pressure, P, is an important factor to affect the MRR of SiC CMP.
The change of the polishing pressure will change the mechanical action, the chemical action and the interaction of the polishing system, so it will affect the material removal rate of the wafer surface.
Conclusion According to the experimental results analysis, the influence of various factors on the MRR of SiC substrate surface was obtained.

The temperature influenced the mechanical and physical properties of material.
A distinct loss in mechanical properties was reported after heating to 6000C.
On the other hand, burning or giving the temperature more on concrete will decrease the properties and ability of concrete especially on mechanical properties of concrete.
Indeed, carbonation is one of the major factors to cause structure deterioration.
Factors affecting diffusion rate include the type and amount of cement, porosity of the material, time of curing, type and quantity of pozzolanic additions.

Therefore, a lot of researches have been done in material properties for its applications[1-3].However, there are very few references to discuss the effects of Young’s modulus of ball bearing on its rolling resistance characteristics.The Young’s modulus is a key mechanical property of materials and varies with different materials; especially large difference exists in the Young’s modulus between the metal and non-metal material, thus the Young’s modulus of ball bearing is a big issue needs to be discussed.
Analysis of experimental Results.The balls’rolling will be affected by the material properties of contact surface when they roll along the raceway of inside ring and outside ring under the radial contact load.
The factors affected by the Young’s modulus of ball bearing on its rolling resistance characteristics are mainly focused on three aspects: the elastic power consumption, contact deformation and the stress distribution, and the characteristic values of the rolling resistant characteristics(including the three aspects above) will decrease with the increase of ball bearing’s Young’s modulus so that the rolling resistant characteristics of ZrO2 are better than that of GCr15, for example, The elastic power consumption of the ZrO2 bearing is about 80 of the GCr15 bearing.

By replacing the interface with sharp change properties with a functionally graded material with a gradually changing composition, a stable interface can be formed for mechanical and functional properties.
These factors affect the change in the segmentation velocity.
Introduction A functional gradient material is a material that has acquired new functions by continuously changing the interface between dissimilar materials or by utilizing the heterogeneity within the material, thereby possessing properties that were previously difficult to achieve simultaneously.
However, there is a lack of knowledge about the various influencing factors related to the formation of the reinforcing particle layer, and a detailed investigation is necessary for practical use.
The following factors are thought to be responsible for these differences. 1.

Introduction One of the most major factors in the microstructural control of structural metallic materials is grain refinement [1].
Fig. 4 illustrates microstructures of the specimens cold-rolled to various reductions and annealed at 500°C for 30 min where significant changes in mechanical properties are observed.
It is anticipated that the carbides play an important role in the microstructural change in annealing and in turn they extremely affect the mechanical properties.
On the other hand, the 25% and 50% cold-rolling illustrated low mechanical properties due to the rolling reduction were small and not enough to obtain UFG like 75% cold rolling.
