There are many factors which affect the fatigue performance of the iron and steel products, such as product surface defects (cracks, scratches, bumps), decarburization, inclusions, etc.
The non-metallic inclusion becomes one of the most important factors which influence the service life of metallic material.
So we have to face with an urgent problem how the inclusions infect the fatigue properties of high strength steel.
The oxide inclusions are generally harmful to the fatigue properties, and the damage degree determines by the differences of their phase, size and location.
One of the reasons why the inclusion will affect the fatigue properties of steel product is that the deformation rate of the inclusion and the substrate is inconsistent.

A scaffold has to satisfy appropriate requirements in terms of mechanical performances and mass transport properties (i.e., permeability, diffusion).
This technique bridges the gap between atomic force microscopy and macroscale mechanical testing, providing the possibility to map the surface mechanical properties [18].

The morphology from the microscope was found that sand grains exhibited different shapes that affect mechanical properties such as bending strength and thermal expansion of Resin Coated Sand.
According to the difference in impurity content and granulometric properties of sand.
The issue depends on many factors.
Physical properties of sand.
However, other factors also have an influence on the defect such as clay content, LOI, %Oolitic, and the grain shape.

Natural conditions that control these factors include the local and regional morphological and lithological setting.
The natural landslide media is in a state of non-saturated which the Infiltration properties and water holding characteristics greatly affects the rainfall infiltration rate.
Seepage properties of landslide 4.1 Geometrical models and mechanical parameters The finite element program of SEEP/W was applied to the analysis of seepage properties of landslide.
This rising line continues to expand, then the unsaturated region gradually reduced and infiltration gradient gradually increases, reducing the mechanical properties of the landslide.
The saturated region was generated and perched water was formed, which reduces the mechanical properties of the landslide

Compared to silicon, GaAs has its own properties: high frequency, characteristics of luminescence and light interception, electromagnetic character and sensing property etc [2].
So it makes the wafer polishing to be one of the main factors in the GaAs product manufacturing [7, 8].
Effects of Technological factors The major technical parameters of GaAs wafers are as follows as thickness, TTV (total thickness variation), TIR (total indication reading), warp, surface residue particle size, and so on [11,12].
Its polishing technology is related to the technological factors, such as the type of slurry, slurry’s concentration, slurry’s pH, agent particle size and potency, load, and the polishing machine’s velocity.
Generally, the mechanical action of slurry plays a significant role initially.

Fatigue properties play a leading role in the reliability and lifespan for the aerospace components in service.
If the structural configurations, dimensional sizes and the material properties are predefined, then the surface quality of a machined component becomes the most important factor that affects performance.
Microhardness traverse Classification and Framework of SI Model The SI model is complicated and involves in many factors which interact with each other.
If we take turning process as an example, then all the factors affected could be classified and defined separately.
The qualitative classification and digital definintion of the abstract factors that affect the SI requirement of machined components make the framework of the SI model be more clear as shown in Fig. 1.

Introduction In the past two decades in developed countries, Polycrystalline diamond, traditional cutting tool replacement products, has been widely used in manufacturing, especially processed nonferrous metals and alloys, because of its high hardness, good impact toughness, abrasion resistance uniformity, excellent heat resistance, thermal conductivity and other properties [1].
One is the mechanical grinding.
The affected layer thickness of rough EDM is about 25 ~ 32 μm, the affected layer thickness of semi-precision is about 15~ 20 μm, and the affected layer thickness of precision EDM is about 5 ~8 μm.
So the time of the thermal process is dominant influence factor.
The influence of the electrode material relative weakening, but it is also one of the factors in effect workpiece surface quality.

The modification of matrix is an important method to improve the mechanical properties of strain hardening cementitious composite (SHCC).
Consequently, it is important to cast SHCC carefully and make sure the even fiber distribution to insure the bridging function and mechanical properties of SHCC.
Therefore, the influence of the preparing processing factors including matrix water binder ratio (W/B), fiber distribution and fresh state rheology on SHCC behaviors are useful for the SHCC design.
However, there are many unknowns, which can affect the interfacial properties when the W/B varies.
Fiber could affect the fresh state properties of cementitious materials and therefore affect fiber distribution [2, 3], resulting in a poor composite ductility at fiber disconnection zone.
