Introduction In recent years, as reported by many researchers [1-9], it has become clear that high strength steels such a high carbon chromium bearing steel, JIS-SUJ2, exhibit complicated S-N properties in the very high cycle regime.
In the case of safety-design for mechanical structures, the duplex S-N property of the structural steels should be clarified as the fundamental reference data [6, 7].

Effect of the size of powder on the Microstructures and Grain Refining Performance of AlTiC alloys CAO Jing1, a, Yongfeng Wang2,b and Chunxue Wei3,c 1,2Department of Mechanical Engineering, Xi’an Aero technical College Xi’an China 710077 3HeNan Industry Design School , Zhengzhou China 450002 amsjingcao@163.com, bwangyfeng@163.com, c weichx060820@163.com Key words: AlTiC；Al3Ti；TiC；grain refiner；refinement mechanism；master alloy Abstract.
As a result, the change in morphology and distribution of TiC and Al3Ti particle has considerably affected the gain refining performance of AlTiC master alloys.
Introduction In the industrial production of Al, grain refiner is often added to liquid Al to improve the microstructure of Al, because the grain refiner can improve the mechanical properties, reduce ingot hot tearing tendency, increase casting speed, improve feeding performance and reduce loose tissue, improve the uniformity of the organization and the subsequent processing performance of Al[1].particularly for the rolled state or extruded Al, the ingot structure is refined to significantly reduce distortion products surface defects and improve the surface quality[2].
AlTiC master alloys have been prepared by contact reaction method, but the author found that the grain size of Ti and C powder obviously affected the refinement of AlTiC master alloys Experimental Methods Experimental Materials Experimental Materials：industrial Al，Al powder，Ti powder，C powder, concrete parameter was shown in Table 1： Table 1 material form Element types Purity Material Shape Particle size[mesh] Al block 99.70% Ingot Al powder 99.60% Ball 200 Ti powder 99.30% Ball 200、500 C powder 99.85% Flake 170、1200 Experiment instrument pit resistance furnace (Maximum temperature 1100)、press (model:AG-10TA)、the electron balance (precision 0.001g)、high speed planet type ball mill (model:Pulaerisette-5)、air blower、graphite crusher、iron rod、iron clamp、copper pouring injection molding and so on.
（4）Comprehensive view of all factors, when there is Al powder (200 mesh), Ti powder (500 mesh), C powder (1200 mesh), the refinement of the master alloys is the best.

This paper reviews the results of gallium (Ga) additions on the properties of Lead (Pb)-free solder alloys in terms of the solderability, microstructure and mechanical properties.
The formation of Cu6Sn5 intermetallics would be beneficial for solder joints in terms of mechanical properties as the fine structure of intermetallic particles in bulk solder could reinforce the solder materials and enhanced their mechanical properties [10,16-17].
Then, with the content of Ga is 0.1 wt.%, the size of primary rod like Zn-rich phase become smaller and will slightly improved the mechanical properties of solder materials.
It is proved with the proper addition of Ga it will slightly improve the mechanical properties by turning the primary rod of Zn-rich smaller.
Hence the mechanical properties of the Pb-free solder are able to attain the best in this component as well [22].

Therefore a thermomechanical processing aimed at reducing wire dimension without adversely affecting its actuating properties will be developed.
Actuating properties described in [6, 13] will be used as a comparison basis.
Before using these modified wires in a morphing structure, we had to ensure that their actuating properties had not been adversely affected by severe plastic deformation stemming from cold rolling.
A characterization of their actuating properties was undertaken.
Considering that the objective was to find a way to reduce the thickness of the SMA wire without adversely affecting its actuating properties, the data on Fig. 5 a) and b) shows that procedure #3 seems to be the best compromise.

The eutectic cells size is influenced by factors such as cooling rate and carbon content or by process related parameters.
Conclusion High cooling rates refine the dendritic network, the eutectic cell structure, and the pearlite inter-lamellar spacing resulting in improved mechanical properties.
Increasing carbon content mainly reduces the amount of the primary phase which negatively affects the mechanical properties.
