However, the poor elevated temperature properties restrict the widely use of Al-containing alloys, owing to the existence of Mg17Al12 phase, as well as Mg7Zn3 in Mg-Zn alloy.
Recently, Jan Bohlen[5] et al. has reported that Zn can modify the rolling texture of ZK10, ZE10, ZEK100, ZKE410 and ZW41.
Tang et. al [15] has reported MgZn phase is existed when 4 wt.% Zn is added in Mg-5Sn alloy, thus the Zn content (1~3 wt.%) in this paper is relative low for forming Zn-containing phases.
Compared with Mg-5Sn sheet, the UTS, YS and EL of Mg-5Sn-3Zn sheet in ED increased about 50MPa, 30MPa and 14%, respectively.
The UTS, YS and EL of all four kinds of alloys increase with Zn added.

One of the elasticity coefficients of a composite, tensile module EL is given by the following
forecast formula
[3]:
EL=EfVf+(1-Vf)Em
In order to simplify the problem, let x represent Vf, and y represent EL.
Vf[%] EL[Mpa] NO.
And the final equation is y * =3.01+0.664x,i.e., EL=3.01+0.664Vf

Piasta et al. studied the properties and durability of Ukrainian igneous rock greaves, including their application to concrete [6].
Kahraman et al. investigated the relationship between UCS and SDI for pyroclastic rocks collected from 31 different locations [11].
González et al. classify the durability of the rocks as high 95-98 % retained weight after 2 cycles and very high >98 % retained weight after 2 cycles [1].
The stone samples that represent very high durability are Huiramba, Joyitas, Comanja, Cuenembo, el Tigre, Mascutan, el Melon, AGC, and el Colegio.
It is important to note that these results depend on their physical characteristics; also, AGC and El Colegio are crushed materials.

Experimental
Basic character of Al-foil.
Measure the impedance between the cathode tab and the Al layer of the Al foil with the multi-meter.
DEC DMC EMC PC EL EC 。
Figure 3 Sealing margin with different solvent and EL Cell corrosion.
If the cathode tab (Ni tab) connects with the Al layer of the Al-foil the electron channel came into being, if the PP damage and the electrolyte contacts with the Al layer of the Al-foil the ion channel came into being.
