Magnesium (Mg) is normally used to improve the mechanical properties of the alloy through the precipitation of the Mg2Si and Al2CuMg intermetallics [1].
Heat treatment is one of the major factors used to enhance the mechanical properties of heat-treatable Al-Si alloys, through an optimization of both solution and aging heat treatment given to these alloys.
Eutectic silicon morphology, viz., particle size and shape, plays an important role in determining the mechanical properties of Al-Si alloy castings.
Once the responses, factors (6) and levels have been selected, see Table 3, the next step is to design the experimental runs.
The factors and their uncoded levels are listed in Table 3.

Its shape and property affect a lot about the bearing ability and the service life.
Therefore, selecting appropriate retainer materials, structure and molding process has become the key to improve the property and reliability of high-speed vehicles bearing[2].
Summing up the analysis above, take the all factors into consideration comprehensively, the injection parameters are selected as: material melting temperature of 295 ˚C; 100 ˚C mold temperature, injection time of 3.69 s; mold material is standard steel Tool TEEL p-20, which nature is: density 7.8 g/cm3 modulus 2.0×105 MPa; The injection molding machine is select default device; maximum injection pressure is 180 MPa; maximum clamping force is 7000 T.
But it is better that locates weld lines in the areas where the force is small, and it can not affect the appearance.
It is 0.03% of the total size of the product, almost does not affect the products quality.

It is necessary, however, to take account of factors such as process-related extreme weld cooling rates, dilution levels, possible nitrogen pick-up during welding, etc.
It is known, however, that mechanical properties suffer only if the σ-phase forms as a continuous network in the microstructure, which occurs at sigma levels above about 4 vol. %.
Both mechanical properties and corrosion resistance are then adversely affected.
Selection of base metals containing adequate nitrogen is an important step in maintaining phase balance in the weld HAZ and improving its properties.

That is because the course of those operations has an effect on a series of factors connected with the whole production cycle.
On their basis, in the heated element, beside the temperature, the microstructure of the material and the corresponding mechanical properties are determined.
Numerical algorithms of such models are based on the equations of heat transport, recrystallization kinetics and grain growth, as well as the correlations between the microstructure of the given material and its mechanical properties.
The radiational heat flux is calculated by means of the method of surface radosity balance and the notion of view factors [17].

However, these porous SiC ceramics were obtained at very high firing temperatures or with low melting point compositions in the SiC grain boundaries which commonly impair the mechanical and physical properties of the material.
The pyrolysis conversion process of PCS as well as the structures and mechanical properties of the specimens will be discussed.
By varying the content ratio of SiC powders to PCS and the starting SiC particle size distributions, pore structures and mechanical properties were evaluated.
area model, the mechanical properties of porous ceramics are determined by the interparticle bonding area [12], so, when PCS content is low, only limited bonding between SiC particles can be achieved, which is the cause of low strength.
The particle size distributions of the starting SiC powders and PCS content are two important factors which affect both microstructures and mechanical properties of the as-prepared specimens.

There are so many factors affecting qualities of deep-drawing parts, such as blank holder force (BHF), the forming force and speed of punch die, die structure, lubricant, material performance, and so on.
The procedure of the optimal BHF determined by NN Comparing this set of control systems to the closed-loop control systems shows that neural network control system can reduce the spring back angle better than that as the material properties changes and it is also more stability and stronger than the closed-loop control system as the training data is enough [20-21].

While thermo-mechanical treatments given to these alloys optimise their mechanical properties, they also result in materials that are susceptible to IGC.
Although the relationship between grain shape and anisotropy in localised corrosion appears clear, other possible contributing factors have not been considered (e.g. texture, particle distributions, stresses).
Thus, because texture can affect the distribution of solute at the grain boundary and regions adjacent to it, there are certain implications for the development of IGC.
The crystallographic relationship between the grain boundary and the precipitate habit plane can affect precipitate morphology [12] and density [13].
Texture may affect whether grain boundaries are susceptible to IGC and the likelihood that IGC will deviate in another direction.

Covalent electron and lattice electron are closely related to the mechanical properties and thermal properties of structure material.
Different content of each element, lead to the different lattice constant of the average atom, thus affecting their crystal structure formed by high entropy alloys.
The method based on EET can get the near results, which have 7%, 5% and 2% deviations, and further we can analyze the mechanical properties using EET.
