Introduction Correlation between the pretreatment of the melt and the macrostructure of the solidification structure is front edge of solidification science.
The heredity of crude material fades partly, thus leads to the Al-22%Si melt more homogeneous both the structure and composition.

Huuki J et al. [2] discussed the influence of ultrasonic burnishing technique on the surface quality for three different materials, namely, aluminum, 34-CrNiMo6 tempering steel and S355J2 structural steel.
Compared with the initial turned surface roughness, the surface roughness values for these three materials decrease by an average of 88% and the finished surface measured an average value of 0.36 ± 0.16μm.

The quantitative measurement of size and distribution of the pores are essential for the material characteristics.
In this paper, Snake algorithm is combined with ACF material images.

The process was developed initially for aluminium alloys, but since then FSW was found suitable for joining a large number of materials.
Monotonic tensile tests Monotonic tensile tests were performed to determine the mechanical properties of the welded and unwelded materials: the yield stress sy, the rupture stress sr, the Young modulus E, and the elongation at failure εr.
