Solar grade silicon is the major material of the PV industry, the method of preparing for solar-grade silicon is a hot spot nowadays.
Commonly, the Metallurgy process uses metallurgical grade silicon as the raw material.
Directional solidification technique enables the solidification structure of materials to put in order along a specific direction, namely as the directional or single crystal structure, which could improve scientifically mechanical and physical properties of materials.

Fig. 1 The basement membrane-like material (arrow)
In our study, compared with adult, newborns’ microvascular endothelial cells were not surrounded with intact basement membrane and only had discontinuous basement membrane-like materials of varying thickness.

The full constraint Taylor model was used to predict the texture changes in the material and the results were compared to the experimental findings.
With increase of the strain up to 30 % the lattice GROD of the BCC constituents increases with 800% with respect to the undeformed material, whereas the increase of GROD in the measured part of the retained austenite is only 200% in comparison with the initial state.

Chemical composition of the parent material is summarized in Table 1.
Two different filler materials - commercial (bainitic) and newly developed (martensitic) metal cored wires were used for welding.
Two filler materials were chosen for preparation of the test welds having quite different chemical composition, namely, different Cr and Ni content and phase transformation temperatures.
