By contrast, Zn and Al contents as low as 0.5-1%, should not lead to any significant precipitation in binary alloys.
Both Al and Zn should thus only play a solid solution strengthening effect that cannot be accounted for the highest strength of alloy 2.

Teng et al. [1] investigated the control of wind-induced vibration of the TV tower mast on Shenzhen Wutong Mountain, which provide theoretical basis for TMD used in suppressing seismic response of high rise structure.
Deng et al. [4] studied wind vibration control experiment based on 500kV Jiangyin large span tower, and verified the design program of tuned mass damper (TMD) and viscoelastic dissipater (VED).
The comparisons of time history responses of transmission tower to El Centro earthquake excitaiton are shown in Fig. 4.

For this purpose we coupled
the VPSC-model of Lebensohn and Tomé [1] with the hardening model of Peeters et al. [2].
In this work we coupled the hardening model of Peeters et al. [2] with the VPSC-model of Lebensohn and Tomé [1] and implemented it in the commercial finite-element code ABAQUS/ Explicit® [7].
The hardening model The hardening model used in this work was developed by Peeters et al. [2] for the hardening in bcc polycrystals for which it is used also in this work.

Later, El-Halwagi et al. [2, 3] and Zhao et al. [4] developed a different method with source and sink composite curves plotted in the impurity load (or hydrogen load) versus flow rate diagram.
Ng et al. [7, 8] extended the PCA to property and concentration based conservation networks with regeneration or purification reuse.
