In general, stainless steel contains nickel content is high enough to produce corrosion resistance and desired mechanical properties.
They show how to obtain optimal mechanical properties of 17-4 PH stainless steel.
But there is another factor that can affect the shrinkage in some parts of the sample, homogenization of powder during the injection process can affect this.

When a product contact parts variety and more complex, if it is unreasonable to establish the knowledge base will affect the speed of retrieval, and even affect the final design.
Case description Examples of mechanical products.
In the mechanical production process requires a lot of equipment, for example ,lathe, its development has gone through several centuries before the formation of today's CNC lathes, CNC lathe also inherited lathe ‘s characteristics, the most important feature is the ability to process rotary parts, where CNC machines and lathes can be used as an example, and CNC lathes as a child inherits the characteristics of conventional lathe, CNC lathe specific examples can be divided into many sub-class instances, each case its own characteristic properties, these properties have similar features but also has inherited, so it is necessary to distinguish between these attributes, and characteristics make a good link.
Each attribute is owned by a specific example, as in Example geometry, shape, symmetry, will be transferred and the like, characterized in that each set of these properties, if the feature attribute indicated by F, p represents an attribute.
We look at an lathe example to influence characteristic attributes of lathe spindle precision which: 1manufacturing precision spindle itself; 2 bearing bore accuracy; 3 bearing the impact; 4 adjusting nut effect; 5 bushing impact; 6 precision of assembly; 7 spindle temperature effects; Select one of the factors continuing downward , we chose 3 bearings precision ,bearings have many attributes, there are precision, bearings to withstand the load, speed and so on.

It has been found that inadequate properties WW are the cause of the frictional resistance increase of 50%.
Thus, the surface layer has a very significant role in modern technology, substantially affecting the durability and reliability of the equipment and the energy lost to overcome the friction while the material consumption and production costs.
One method of processing a very accurate for providing a surface layer with favorable performance properties, surface treating plastic - burnishing.
In the first step, on the semi-finished product surface the regular asperities of the required outline (triangular, arc, arc-line, or other) and parameters dependent on the desired surface layer properties is embossed.

Content of functional fiber was another important factor influencing the properties.
Mechanical and wear-resistance properties were observed relatively stable.

d) Mechanical properties: Specifically for this problem the Young modulus of silicon (170GPA), Poisson ratio (0.17) and material density (2330kg/m3) were considered, even when, after the manufacturing processes, some changes appear like residual stress, dilatation or undesired strains.
Some authors have proved that the Young modulus of silicon and polysilicon layers measured after the manufacturing processes may range from 149 to 170 GPa [8-13] depending on several factors like the crystal orientation or the deposition process.
Material porosity after deposition may also affect the stiffness of the microstructure.

Therefore, the waist width should be increased to improve the mechanical properties of the whole rail, then augment the mass of the rail.
The corrugated waist rail is one important way to improve the economic properties of classical rail, and it has great significance on the economy and science.
The FEM analysis on corrugated waist rail already test that this special kind of rail structure is superior to classical rail on the lateral flexural, longitudinal stability and dynamic mechanical properties[4].
Fig.6 Rolling force under different reduction 4.2 The Influence of Rolling Speed Rolling speed is a main factor affect deformation velocity, is also main parameter affect rolling force.
Main conclusion is as following: Main factors, such as relative reduction, rolling velocity and initial thickness, can change rolling force, the influence of relative reduction is larger.

Introduction The rheological properties of a polymer melt are very important in processing but are complicated by a number of factors such as flow rate, pressure and temperature.
All these factors can affect the rheological properties of polymer and rubber melts [1, 2].
The rheology of polymer melts is considered to be one of the most important factors in determining the properties of a polymer product especially for those which require good flow properties in polymer processing, fabrication and molding process.
The addition of carbon black in rubber matrix as a reinforcement is to modify the mechanical properties of the finished product and to control the viscoelastic behavior of the compound properties.

The tin content in the aluminum-tin alloy is an important factor that affects the mechanical properties and friction properties of the alloy; the medium and high tin aluminum alloy has better compliance, embedding, seizure resistance and high temperature resistance [7- 8].
Studies have shown that when ≤ 0.001 s-1; when ≥10 s-1, when 0.001 s-1 ≤≤ 10 s-1, changes along with the changes of strain rate and temperature; it is also affected by the thermal properties of samples and the thermal conductivity coefficient [18].

The possibility of specific and local influence on the properties of these materials opens up to new potentials concerning the application of these materials.
Therefore it is necessary to minimize and locally limit the thermal load of locally hardened materials and stuctures on the one hand, and thus keeping the influence of the joining process onto the materials related factors for strength increase as small as possible.
But, on the other hand the chosen welding process has decisive influence on the resulting component properties so that even the joining process can contribute to the improvement in structure or component property.
HF welding being a resistance welding process with geometry and material dependant inductive or conductive energy application, is an innovative and fast joining process for welding of high-strength metallic structures with graded properties.
This first phase pays particular attention to the analysis of possibilities for local influence on the weld seam properties.
