By continued pressing a more advanced deformed substructure was obtained after conducting two deformation passes (8 pressings), which yielded the equivalent strain of ε~2.32, four deformation passes (16 pressings, ε~4.64) and 8 deformation passes (32 pressings, ε~9.28).
Locally observed, the more advanced process of polygonization contributed to formation of regular equiaxed subgrains free of dislocations.
Considering transformation characteristics of deformed structure the mechanism, which contributes to structure refinement, as concerns of the only advanced deformed substructure transformation within macro- sheared bands to polygonized subgrains, excluding primary stage of the large grains subdivision by- macroshearing, the local dynamic reco- very is active and no more microshearing.
The engineering stress-strain curves of post-deformed and annealed Al are presented in Fig. 7.

The extent of stray grain formation ahead of the advancing solidification growth front was calculated based on the model of Gäumann et al [13].
The model was used to calculate Φ, the area fraction of new equiaxed grains (stray grains) that nucleate and grow ahead of the advancing dendrites.
Since the formation mechanism for stray grain formation during weld solidification is based on the extent of constitutional supercooling ahead of the advancing solidification front, changes in composition which reduce the extent of constitutional supercooling will help to improve the resistance to stray grain formation.

It is decreased in advanced age and cataract.
The failure of the outlet valve mechanism impedes the emission of waste, causing stagnation and consequently, their dehydration by decantation (there is relative dehydration of the lens as one ages; the lens ages, alpha-crystalin is converted into insoluble albuminoid; as the lens ages potassium content decreases, the gamma-glutamylcysteinyl glycine decreases in advanced age and leads to cataracts [4]), the viscosity of the mobile media in the lens accumulates and increases degrading the process of mass transfer.

The fatigue life of parts in the engineering practice is estimated using Wohler (SN) curves and Goodman diagrams.
This will further ease and promote the incorporation of the residual stress in the fatigue life calculations and make the data more accessible for practical engineering use.
