These results are similar to those reported by Nachod and Wood, (1944) [37] who investigated the exchange of alkali and alkaline earth metals on zeolites and, also by Nabi et al. (2007) [38] and Nilchi et al.(2006) [39].

Introduction There is an increasing use of magnesium alloys for lightweight structural and functional parts in the automotive, aeronautical and electronic industries, due to the attractive combination of low densities (1.74 g/cm 3 versus 2.7 g/cm 3 for Al) and high strength-to-weight ratios, along with good damping capacity, castability, weldability and machinability [1,2].

Boller et al [4] introduced the nondestructive test method for the detecting of existing defects and classifying their types.
The welding speed was 16m/min and the power ranged from 230kW to 270kW, which can reproduce 3 different welding types classified by Haga et al [5].
The mechanism of the penetrator has been extensively studied by Haga et al [5].
This result was nearly coincided with the study of Taira et al [11].

Similar results were also reported by Bray et al. [5] for Aluminum Alloy 2024 samples that had been solution treated and aged at 190°C.
Mukhopadhyay et al. [9] attributed this softening to reversion (dissolution) of clusters of solute (Cu and Mg).
Bray et al. [5] did not agree with Mukhopadhyay et al. [9], stating that in the early stages of aging, the clusters did not go into solution, but increased in quantity.
In fracture of high strength Al-alloys, intergranular damage is induced by growth of micro-voids around coarsened precipitates.

Gente et al[3] simulated (μ=0.3) the high speed cutting process of Ti6Al4V at 300m/min and 6000m/min, and verified the simulated results through turning experiment, and so did S.
Lu et al[4] at 166m/min.
Wang et al [5] studied (μ=0.2) the shear failure model in high speed orthogonal cutting of Ti6Al4V, the results showed that the chip is continuous when the shear failure model was not used, and on the contrary, obtaining the serrated chip, which is much similar to the photo of Scanning Electronic Microscope (SEM).

One of the first detailed investigations of the jet in cross-flow has been reported by Bergeles et al. [5].
Kelso et al. [8] investigated experimentally the genesis and development of vortical structures in the jet cross-flow interaction.
Moussa et al. [10] studied the mixing of the jet in a cross-flow.
A jet in a cross-flow has been studied numerically too (see Yuan et al. [12]).
Jovanovic et al. [13] analysed the effect of a discrete imperfection inside the short perpendicular hole.

The presence of such facets are well documented for Al, Au, AuCu3, and Ge [18-21].
Westmacott and Dahmen observed that a small Al grain embedded in another Al grain had a polyhedral shape at low temperatures [26].
