The basis of modern macrosegregation theory was outlined by Flemings et al. [4-6].
This paper focuses on the numerical study of solidification and macrosegregation defects formation in the system Al-4.1wt% Cu.

This paper reviews a few of these recordings on Al and Mg MMCs and also some future development in this field.
The maximum value of hardness of 87.5 HV of the Al6061-CNT composite was obtained at 620˚C.Kim et al [3] studied the friction and wear characteristics of CNT-Al composites manufactured by hot pressing (HP) and spark plasma sintering (SPS) processes.
The effect of ball-milling time on mechanical properties of CNT-Al composites was studied by Liu et al [6] and the CNT-Al composite, when produced by ball-milling for 6 hours, had 42.3% more yield strength when compared to Al matrix, manufactured by same processing history.
El Borady [11] studied properties of CNT-Al strips and the Al–0.5 wt. % CNT strips exhibited improved tensile strength, yield strength, Young’s modulus as well as lower density.

El Centro earthquake motion, Taft earthquake motion and artificial earthquake motion are as inputted earthquake motion in shaking table tests, which time history and frequency spectrum, are listed in figure 2.
Analysis of testing results 4.1 El Centro motion input The results of Testing I (under El Centro motion, PGA 0.222g, the gap is 0.01m) and Testing II (under El Centro motion, PGA 0.221g) were listed in Table 8, 9, and 10.

The driving frequencies were decreased when the EL (elastic length) of the stator was increased.
The maximum displacements were obtained when the ration CL/EL was 0.7.
The resonant frequencies were decreased when the EL (elastic length) of the stator was increased.
Al has maximum displacement, as a sequences of SUS, steel, copper, and brass.
When the CL (ceramic length) / EL(elastic length) was increased from 0.5 to 0.7, higher speed and torque were obtained, but the speed and torque were decreased when the CL / EL was increased from 0.7 to 0.9.

After castings the casting rings were left to cool by it self, as it is usually done at laboratories Ganzarolli el.al.and Strandman el.al
Conclusions Our study is in accordance with the study of Issac. el.al. demonstrating that with the increasing number of casting the hardness also increases and mechanical values change.
The difference with the study of Ozdemir. et al.
