Extensive studies have been carried out to explain the fact that the microstructure of weld and CGHAZ plays an important role in defining the mechanical properties of the weld zone [2-3].
Besides the microstructure, the alloy element also plays an important role in the properties.
The toughness of the HAZ is strongly influenced by metallurgical factors such as the M/A constituents, the microstructure of the matrix and the grain size.
The type and distribution of M/A constituents can affect the toughness greatly.

Therefore, the withdrawal rate is the main factor affecting the as-cast microstructure of the alloy.
Its growth morphology directly affects the distribution of casting defects and has an important effect on the mechanical properties of single crystal superalloys.
There are many factors to affect the rupture property of Ni-based single crystal superalloys, such as dendrite morphology, residual eutectic, pore, TCP phase and γ¢ phase morphology, etc.
The internal pores of the alloy is also one of the important factors affecting the rupture properties.
The fracture microstructure analysis shows that the factors affecting the rupture life are mainly related to the precipitation of TCP phase, pore content and γ' size.

Mechanical Properties Equipment and method.
It could be seen that mechanical properties increased with the curing temperature elevated.
There were two factors that might cause these changes of mechanical properties.
As a result, the fracture process was speeded up, and the mechanical properties were poor.
Meanwhile, curing temperature also influenced on mechanical properties at 125-225oC.

On Yarn Unevenness Test and its Influence Factor Analysis Jing Jin 1, a, Jiangping Wang2, b, * 1College of Mechanical & Electronic Engineering, Xian Polytechnic University, Xian, China 2School of Mechanical Engineering, Xian Shiyou University, Xian, China ajinjing5959@sina.com, bjpwang@xsyu.edu.cn, *corresponding author Keywords: Polyester POY, yarn evenness, test, influence factors Abstract.
So the factors which affect filament evenness are complex.
According to the principle of the evenness tester, variation coefficient of yarn unevenness is based on the electrical properties of the capacitor plates and the geometrical factors of measuring space, and is independent of speed in which the sample passes through the gap between the plates.
The paper analyzes the test influence factors when the capacitive evenness tester is used to measure polyester filament yarn unevenness.

This research was study the effect of resistance spot welding process on physical properties.
Factors affecting the tensile shear and nugget size are the most welding current 10,000 amp., welding time 10 cycle and electrode force 1 kN. were tensile shear 7.13 kN. and nugget size maximum 6.75 mm.
Because if the selection condition on access to inappropriate, would have affected the mechanical property which reduced the strength of work pieces.
The experimental design of full factorial design to be the main factors effectors affecting significantly.

Thermoelectric Properties of Silicon Germanium Alloy Nanocomposite Fabricated by Mechanical Alloying and Spark Plasma Sintering Zhenye Zhu1,a , Shilei Guo1 1Division of Materials Science and Engineering, Shenzhen Graduate School, Harbin Institute of Technology, Shenzhen, PR China azhuzy@hitsz.edu.cn Keywords: SiGe, mechanical alloying, spark plasma sintering, thermoelectric properties Abstract.
The effects of different nano-Si70Ge30B5 doping content on the thermoelectric and phase properties were studied.
Because SiGe alloys have good thermoelectric properties and superior long term reliability at elevated temperature, so they are suitable candidates for high-temperature thermoelectric applications.
In recent years, many studies have been done to further increase the thermoelectric properties of thermoelectric materials by using a nanostructured approach.
The thermoelectric properties were further improved through the adjunction of nano-Si70Ge30B5 particles.

The paper properties such as roughness, gloss, surface wettability and other factors have great influence on the dot reproduction attributes of presswork, and different paper factor has different effect weight on the dot reproduction.
The grey relational analysis is a multi-factor statistical analysis method, which is based on the sample data and the grey incidence of various factors and is used to describe the strength, size and the order of the relationship between the factors.

The correlation between all factors and sub-factors were constructed an incidence matrix, and the influence between different factors could be obtained by analyzing the matrix [4].
The penetration and diffusion of ink on paper surface was affected by the roughness and surface wettability of the paper, thereby led to the mechanical dot gain.

The description of the basic material for the printboards production is given, its basic physical properties are formulated, the features of machining are shown and the range of problems that arise in this case is determined.
It is shown that nesting and, as a consequence, an increased content of glass fibers through a chain of interrelated factors affects the quality and reliability of the printboard operation and the entire product as a whole.
Glassfiber surpasses textolite by its mechanical properties, heat resistance, resistance to aggressive environment and practically does not deteriorate its properties when exposed to air for 20 years or more [5].
This article has a application value, because the increased content of glass fiber and too dense fiber laying for TSP and MLP through a chain of interrelated factors ultimately affects the quality and reliability of the boards.
During the experiments, the following factors were evaluated: availability and size of characteristic defects, wear resistance of the cutting tool (in terms of the number of machined holes and the value of the burrs of the foil).
