The processes which include injection debinding and sintering were studied as well as the properties.
Experiment Process Properties of Powders.
The uniformity of feedstock directly affects subsequent processing steps as well as properties of materials.
Although performance of products are related to many factors, in many cases, the sintering process has great impact on the final products of microstructure and properties, even decisive influence.
So the sintering atmosphere affects the process of sintering densification and the final mechanical properties.

These works focused on studying of the variation of the welding parameters that affected to vary the machnical properties such as a fatigue strength, an impact strength, a tensile strength, and a sound microstructure of the joint [4-8].

Compared with the experimental results show that the elastic theory analytical solution overestimates the capacity of members, using experiment method can obtain more secure mechanical behavior of high-strength angle steel member with an eccentric load at one end.
At the eccentric end, mechanical properties and deformation is close to both ends of the eccentric compression, but for the axial end, mechanical properties and deformation process is relatively close to the axial compression Angles.
Compression bar of bearing capacity is affected by end constraints, initial eccentricity, initial bending, residual stress, and many other factors [5].
Conclusion The stability bearing capacity of single-angle compression member with a eccentric load at one end are studied by the analytical method, considering the experimental member boundary conditions issue, the analytical method can not accurately simulate conditions of end restraint, the initial defects and other factors, the resulting test value higher than the analytical value of 40% to 60%, also indicating that such member boundary conditions can not simply end restraint seen as hinged or fixed.
Analysis of mechanical behavior of members by experiment method is more reliable and safe than the analytical method.

The luminescent properties of YBO3:Eu3+ phosphor with 25 mol% doping concentration of Eu3+ is optimal.
Introduction Much attention has been paid to rare earth borates due to their stable physicochemical properties , ideal vacuum ultraviolet (VUV) absorption and non-linear optical properties [1,2].
Phosphor is one of the important factors affecting the PDP device performance [3,4].
The luminescent properties were measured by a Hitachi F-7000 type fluorospectrophotometer at room temperature (PMT Voltage: 500V, Scan speed: 1200 nm/min).
Result and discussion Effect of ball-milling temperature Calcining temperature is one of the important factors affecting the phosphor luminescent intensity.

It is at this stage that fundamental decisions are made, which can significantly affect reliability.
At the conceptual stage of design, the design team must consider simultaneously a number of multi-disciplinary factors.
Independent operation is achieved at an active interface if the variation of the force in reserve for performing each function is at a minimum) and unity (A component should have sufficient strength for the static and dynamic loads it has to carry), as significant factors of the external properties of performance, economy and reliability of mechanical systems, As shown in Fig 1.

In order to obtain excellent ballistic performance, some adhesive with a variety of content of nano-SiO2 was prepared, and mechanical properties and ballistic test were conducted.
The targets with adhesive added in 20% nano-SiO2 express the best anti-bullet properties.

All those things can strongly affect the ballistic performance.
As discussion above, the adhesive with 20%nano-SiO2 express good properties.

Nevertheless, in those works, limited or no attention was generally paid to the crucial issue of the spatial variability of material properties within AM, which can produce critical forms of mechanical response and premature failure.

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.

The materials with excellent mechanical properties and weldability have been widely used for petrochemical plants and nuclear industry.
A weldment consists of three zones from the material's micro-structural viewpoint: weld metal, heat affected zone (HAZ) and base metal, and each exhibits different mechanical and fatigue behavior.
