Keywords: water atomization; iron powder; high compressibility; influence factors Abstract: In this paper, the influence factors on high compressibility water atomized iron powder LAP100.29 were studied such as the processing parameters, the proportion of coarse particles, powder oxygen content and impurity.
Therefore, in order to improve the production techniques and competitiveness of the domestic atomized iron powder, it is a significance to study the influence factors on the compressibility of iron powder. 2 Experimental Methods Manufacturing process of water atomized iron powder is carried out according to the normal process specification of the production enterprise.
Therefore the analysis of the factors affecting the compressibility of water atomized iron powder was carried out from the various process parameters, such as melting temperature, purity of molten steel, reduction temperature, particle size and distribution, etc. 3.1 Optimization of powder production process According to the analysis of current production process of water atomized iron powder, the production process needs further optimization and improvement in order to obtain the green density more than 7.20 g/cm3 under the pressure of 600 MPa.

TEST OVERVIEW 2.1 Calibration POI-1000M Spin Balance Machine is the model of Mass Properties Measurement machine and can be considered as the heart of this equipment.
That’s why the installation process and environment factor should be well prepared to minimize the offset which may affect the result.
Temperature change may affects the properties of the part itself where the increment on temperature will increase the MOI of the part and causing unbalance due to sudden changes in temperature.

Permeability coefficients and defects of the impermeable wall are the most factors of affecting effectiveness of dyke reinforcement.
Numerical Calculation and Analysis In this paper, according to the results of geological exploration the selected typical cross section is 7+000, and the finite element method is applied to analyze properties of the counterparts of the original dyke [4, 5, 6].
The physical and mechanical indexes of the dyke and foundation are given in Table 1.
Table 1 The physical and mechanical indexes of soil layer Position Layer NO.
So the permeability coefficient of the impervious wall is a key factor which affects the seepage quantity of the dyke.

But porous metals have outstanding physical and mechanical properties which providing them double natures of function and structure, and are applied in many fields of science and technology.
Furthermore, these behaviors are connected with laser mode, laser input energy and powder properties.
Seen as figure 3, the processing factors include laser power, scan speed, scan space and layer thickness which will interact with powder size, shape, size distribution and their thermal properties.
Therefore, it is important to focus on the interactions of pretext factors and find internal laws from these combinations of factors.
Figure 3 Interaction factors in SLM Figure 4 Interaction results of factors on the forming of pores As for research methods, there can be three items according to time and logic(figure 5).

These cutting forces are affecting the surface qualities and also causes delamination damage.
The favorable properties like high dimensional stability, high strength and good machinability increase the use of MDF material [5, 7 and 10].
Prakash and Palanikumar [10] carried out drilling tests using Taguchi design of experiments and RSM to evaluate the thrust force developed and revealed that the feed rate and diameter were the factors mainly affecting the surface roughness in drilling of MDF with PVD TiN coated carbide step drill bits.
Control factors and their levels are shown in Table 1.
Figure 1 CNC vertical machining center and sample of thrust force plot Result and discussion Nowadays the use of MDF panels is increased in wood working industries because of their superior properties.

The results show that flow stress is affected by deformation temperature significantly and declines with increasing temperature.
For TRIP steels, the researchers mainly focused on mechanical property, welding performance and the mechanism of phase transformation.
By heat treatment experiments of two kinds of TRIP steels, the relationship between mechanical properties and deformation mechanism of TRIP steels were established [9].
Dan [3] studied the influence of strain-induced martensitic transformation on mechanical properties based on a developed Tomita-Iwanmoto model coupled with mixed hardening law of four phases and anisotropic yield function.
Due to a good adaptability towards finite element (FE) interface routine and a comprehensive description of strain rate and temperature affecting on yield stress and strain hardening, J-C model and Z-A model are extensively used.
