In previous work, Bai et al. [5, 6] have shown that the stop coiling temperature has a strong effect on the microstructure and Nb(C, N) precipitation behavior, then on the final mechanical properties.
Lee et al. [9] suggest that the kinetics of the Nb(C,N) precipitation is fastest at a temperature somewhat lower the austenite-to-ferrite transformation temperature.
Bai et al [6] have found that the effect of cool deformation on the yield strength for steels (0.045C-1.5Mn-0.045-0.072Nb) increased due to the acceleration of Nb(C,N) precipitates in ferrite by deformation.
As well, Wei et al. [10] have found that cool deformation leads to Cu precipitates between 40 and 50 nm but not in the aged only condition.

Some materials used are oxides of Aluminum (Al), Magnesium (Mg), Iron (Fe), Nickel (Ni), Tin (Sn), Zinc (Zn), Zirconium (Zr), and silicon (Si).
However, research conducted by Ogolo et al. showed that the most effective nanoparticle is silica which produces a high percentage of oil recovery [7].

Fiber-cement composite degradation becomes a precursor which has been demonstrated by Gram [8] and Mohr et al. [12].
Silica fume in a large number (30% of the amount of cement) is believed to reduce the degradation of the composite, according Toledo Filho et al.[14]; Gram [8]; Bergstrom and Gram [3].
The formation of hydration products around the fibers caused by the existence of pozzolanmay restrict fiber swelling.This matrixstrength improvements with increasing age due to continued cement hydration were notconsidered as by Mohr et al. [12].

However, for high strength Al-Zn-Mg-Cu and Al-Cu-Mg alloys, silicon together with Al and other impurity elements, such as iron, forms Si-rich phases that are brittle and have a Young’s modulus and expansion coefficient different to the a-Al matrix, so act as stress raisers and points of weak coherence, leading to a reduction in the mechanical properties, especially fracture toughness [3-4].
The main phases are -Al and TiAl3, which should be the particulates.
The main chemical elements are Al, Ti and less Si, and the atomic concentration ratio of Al and Ti is close to 3.
