Evaluation of Permeability of Interdendritic Channels for Al-Cu and Sn-Pb Alloys M.
In this paper a model developed by the authors is used to predict the permeability in directional solidification of Al-Cu and Sn-Pb alloys.
Piwonka and Flemings [3] carried out the first measurement of permeability forcing liquid lead throughout solidifying Al-4.5 wt pct Cu.
%Pb the secondary dendrite arms spacings obtained by Rocha et al. were used.
For the Sn-Pb alloys are adopted the equations proposed by Rocha et al..

Fig. 1 shows alloy Al-1 gives more noble value of OCP, alloy Al-3 recorded more active value of OCP, while alloy Al-2 shows value of OCP between those of alloy Al-1 and alloy Al-2.
After polarization process, the corrosion potential (ECorr) of Al-1 is found to be more positive than those of Al-2 and Al-3, while that of Al-2 is slightly electropositive than that of Al-3.
Capacitance value of Al-3 alloy is much higher than Al-2 and Al-1, implies that more corroding area on the Al-3 alloy surface.
The corrosion resistances of Al-Zn alloy in natural chloride solution decrease with the following order: Al-1 > Al-2 > Al-3.

Experimentally, in the case of no phase separation, Makino et al.[2] reported the maximum Mg composition concentration(x) in MgxZn1-xO ternary alloys grown by pulsed-laser deposition is 0.33 while the Takagi et al.[3] reported that the available maximum magnesium composition concentration in the single-phase wurtzite MgxZn1-xO ternary alloys is up to 0.51.
Experimentally, in the case of no phase separation, Makino et al.[2] reported the maximum Mg composition concentration(x) in MgxZn1-xO ternary alloys grown by pulsed-laser deposition is 0.33 while Ohtomo et al.[11] have reported a solid solubility of 0.35 of MgO in ZnO in pulsed laser deposited thin films, Thin films with x up to 0.20 exhibited a preferred c-axis orientation, whereas for x>0.20, the patterns were similar to that of bulk ZnO.[12] Tanaka et al.[1] have proposed the use of a high-quality ZnO buffer layer to firmly fix the crystal structure of the layer successively grown on it to wurtzite and, as a result, the growth of single-phase wurtzite MgxZn1−xO with magnesium content x of as high as 0.51 with band-gap energy of 4.45 eV has been reported.[3] These results are all in the region we calculated as shown in Figure 2.
