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].

It can be found that Ti2AlC is the dominated phase from the Ti-Al-TiC system.
No any trace of the starting constituents was found, which testify the feasibility of Al2O3 reinforced Ti2AlC composites by incorporation of the in situ reaction of Al and MoO3 into Ti-Al-TiC system.
In their work, the optimum molar ratio of Ti : Al : C was 3 : 1.1 : 1.8.
The deviation from theoretical composition in the starting materials is attributed to the volatility of Al melting at high temperatures.

A.Onyszko et al.[4] introduced Bridgman preparation technique to produce the CMSX-6 superalloy turbine blades, and, Stanisaw Roskoszso et al.[5] investigated methodology of quantitative evaluation of porosity, dendrite arm spacing and grain size in directionally solidified blades made of CMSX-6 nickel alloy, but they did not make a deeper investigation about the process parameters such as pouring temperature.
In the late stage of solidification, the content of Al and Ti which are in the remaining alloy melt is rising continuously.
The segregation of Al and Ti are more serious, so the size of eutectic is slightly larger, but the number is smaller.
