Azuraida et al. (2015) [5] is also in agreement to this reasoning and confirmed by the data shown in the FTIR spectra.
According to Ruller et al. (1991) [6], bombardment of gamma rays into the glass sample caused the formation of void in the glass network.

The objective of this work is aimed to confirm the theoretical results that An et al [5], Bennacer et al [6] and Verhoeven et al [7] found that the IVB method reduces the micro-segregation as compared to the VB method, producing samples more homogeneous, and the influence of convective flows in the formation of dendrites in eutectic alloys.
The graphics shows that the density profile and distribution of the solute are closer to the nominal values, confirming the reduction in convection and consequently the micro-segregation of the solute in the IVB method when compared to the VB method, as predicted by An et al [5] and Bennacer et al [6].
The results obtained by both densitometry and microstructural analysis are consistent with the theory of Verhoeven et al. [7].

Barsoum and El-Raghy [9] successfully synthesized high purity Ti3SiC2 poly crystals by hot-pressing (HP) or hot isostatic pressing (HIP) a powder mixture of titanium, graphite and SiC, in which TiC phase was reduced to an amount of about 2.0% by volume.
Sun, et al. [11,12] fabricated bulk samples with about 99% Ti3SiC2 by pulse discharge sintering Ti, Si and TiC mixture at relative low temperature of 1250~1300 o C.
Recently, Zhu et al. [13] investigated the effect of aluminum on the reaction synthesis of Ti3SiC2 and fabricated essentially single-phase Ti3SiC2 with addition of aluminum by HP or SPS technique.
Though 0.05 Al (molar rate) was added, the sample still contains 21.6vol.% TiCx.

Coskun, R. et al found that, the use of itaconic acid and AAminitiated grafting with benzoyl peroxide can was increased from 3% to 76.1%compare with grafted with itaconic acid, 90:10 is two kinds of optimum ratio of monomers, the grafted PET has good ability of adsorption of heavy metal ions[2, 3].While the use of itaconic acid and Methyl acrylamide (MAAm) and crotonic acid and MAAm co-grafted with class effect, the DG increased from 3% to 13.7%[3], andfrom 2.2%to 23.9%[4].
Zhang, J.F. et al. useda cationic monomer N, N'-dimethylaminoethyl and an anionic monomer AAc to modified PET, found that the grafting could modified zeta potential of PET from +39 to -58 mV[6].

In this analysis, δ for the solutes Al, V, and Fe was calculated from the respective 12-coordinate metallic radii and δ for the interstitial O was estimated from the volumetric change associated with O additions [5].
Foltz et al also observed that slip was readily transmitted into the beta phase given a Burger’s orientation relationship between the alpha and beta phases [13].

Clark et al. [1] first presented a SMA-based damper, which consists of two groups of parallel pre-tensioned SMA wires.
Dolce et al. [2] improved this damper by adding another group of SMA wires, functioning as re-centring group.
Robert et al. [3] presented an important class of SMA damper - the center- tapped (CT) device, which is studied the most currently.
