The structure and properties of the composite system are influenced by many factors, such as pH [7], ionic strength [8], polyelectrolyte molecular weight [9], temperature [10], etc.
When solid shows micro-deformation and liquid can flow freely, the composite system shows different mechanical properties from that of conventional solid and liquid.
This kind of mechanical properties lies between elastic solid and viscous liquid.
Even the weak force can change its property sometimes.
(2) Affects of Salt Content Changes in salt concentration can affect the configuration of polymer coils, which may contract their size and shield surface charges of microspheres and HPAM which weakens the interaction between microspheres and HPAM.

The VSM characterization results showed that different aging times did not affect the barium hexaferrite nanomagnets' magnetic properties.
The physical properties of barium hexaferrite are influenced by various factors such as the manufacturing process, chemical composition, temperature and sintering period, and type and amount of substitution.
However, there was a slight effect on the magnetic properties of the nanomagnets.

In order to simulate the actual forming process of plate as much as possible and increase the prediction accuracy of residual stress, we improved the original finite element model of pressure head [9] by taking into consideration the smooth transition of the surface of square head , the screw hole in the center of pressure head and other factors.
However, due to that theoretical derivation process introduced too much hypothesis, and without considering some factors such as the inside displacement of neutral layer, the thinning of thickness, the contact friction between the plate and pressure heads, the differences between the two results are inevitable.
These factors are the reasons why the residual stress peak value is greater than the theoretical value of residual stress when the plate is under pure bending.
(3)The residual stress level of the forming piece is mainly affected by its mechanical properties, thickness, deformation and some other factors.

Properties of tool materials are improved obviously.
Carbide grain is generally less than 2μm~3μm, so PM HSS has good mechanical properties.
The main AL2O3 composite cutting tool were Al2O3, add small amount of carbide and oxide, which has good mechanical properties.
The Si3N4 composite cutting tool is better than Al2O3 composite cutting tool in mechanical properties.
In addition,it has fine properties such as high thermal stability, good wear-resistance, low friction factor, good chemical stability, mainly processing ferrous material and various kinds of difficult-to-machine materials [13].

Among them stamping formability is the most important aspect, which includes basic mechanical property, formability and effects of zinc coating in stamping process.
Therefore research on stamping formability of hot-dip galvanized sheet and analysis of its influencing factors are meaningful[4].
The initial and boundary conditions of the simulation are also set, including material properties of sheet, boundary of sheet, punch and die, blank holder force, coefficient, initial speed of binder, speed of punch etc.
On the one hand, the zinc coating leads that crystal structure, chemical composition and mechanical property of galvanized sheet are totally different with those of bare board.
Effect of microstructure and texture on formability and mechanical properties of hot-dip galvanized steel sheets [J].

The damage of the printed wring assembly (PWA) was treated as one of the main factors of the failure of electronic equipment.
So, it’s clear that vibration is one of the important factors lead to failure of electronic equipment.
Also, random vibration and impact is one of the key factors for the reliability of packages [10].
The mechanical properties of the parts made up of the PWA were list in Table 2.
The contributeness of each mode in each direction maight be illustrated by the participation factors.

High speed cutting used smaller cutting parameters thus can be applied directly to the finishing process and parts with poor mechanical properties, such as thin-walled work piece, aluminum alloy parts and parts of hard brittle material, etc.
The high-speed machining, affect the service life of cutting tools are the major factors: tool materials and the work piece material the matching relation, cutter geometrical shape, processing methods, cutting capacity, cutting vibration, cooling liquid etc.
As compared to feeding, cutting depth of the change has the effect of surface roughness is not obvious, figure 3-4 for high speed milling 45# steel cutting depth when the surface roughness of the influence law of the curve, although when cutting depth increases, the surface roughness also increase, but its change small scale, the curve is relatively flat, it indicates that the three factors of cutting processing, cutting depth on the surface processing the influence on the quality of is the smallest, so the high-speed machining, can increase cutting depth by appropriate to improve manufacturing efficiency.
To feed the cutting force is the main reason for the increase, and cutting force directly affect the process stability.

To determine final-gauge properties, the microstructural evolution in
all process steps needs to be suitably modelled.
Another requirement for TPM is the relationship between final-gauge microstructure and properties.
These properties include mechanical (e.g., ultimate tensile & yield stress, failure strain), corrosion behaviour, and surface appearance and Fig. 2: Evolution of microstructural parameters during casting and homogenisation.
• dispersoid size and number affecting pinning of dislocations and GBs.
Table 3 illustrates the effect of various factors on the post-homogenisation microstructure.

To solve these problems, surface treatments are widely used to improve properties of titanium alloy [3, 4].
Physical, chemical and mechanical properties of material surface are important components of the whole performance, especially on special occasion and therefore surface properties play an important role.
Material properties like mechanical strength, hardness and corrosion resistance depend on the microstructure (i.e.
Generally speaking, material properties mainly depend on a number of factors like grain size, phase composition and residual stress.
HCPEB can change these factors to a great extent.

Hence it is important to have a
method for estimating the hydrophilic/ hydrophobic surface properties of such particles to select a
suitable surface modification strategy.
Therefore, it is generally accepted to use the phenomenon of capillary penetration of liquids into porous media to determine the wetting properties of particles by measuring the penetration velocity of well-defined liquids in a powder packing.
Introduction The incorporation of organic or inorganic particles suspended in an electrolyte bath during metal electrodeposition results in composite coatings with better and sometimes new mechanical and chemical properties [8].
Dedeloudis and Fransaer [4] showed that the way in which a metal electrodeposits around a particle on an electrode depends strongly on the surface properties of the particle and the electrode.
Generally, the selection of the measuring liquid system depends on the chemical properties of the system.
