Abstract.
Su et al. (2019) found that pH values of 4 and 6.5 were favorable for the degradation of orange II using α-FeOOH@GCA in the presence of persulfate ions [19].

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.

The second type is composed of Al and Mn referring to Al8Mn5.
Investigations of Tanno et al. [18] and Diophone et al. [21], occupying with caliber rolling of AZ31, show similar results.
These results confirm investigations of El-Morsy and Farahat [43] on aged AZ61 wrought magnesium alloy.

Introduction
True stress–strain curves can be obtained using tensile (Bridgman [1]; Cabezas and Celentano [2]; etc), torsion (Bressan and Unfer [9]), ball indentation (Lee et al. [5]; Nayebiet al. [6]), punch (Campitelli et al. [7]; Isselin et al. [8]), compression (Choi et al.[9]; Lee and Altan [4]; Ebrahimi and Najafizadeh [13] ) and other tests.

Aruda et al. [4] showed that strain hardening observed for Polymethyl methacrylate (PMMA) tested
under compression is due to the temperature rise during deformation.
These results confirm those of Rittel et al. [6] obtained by means of thermocouple technique.
Bauwens et al. [11] and Ghorbel et al. [12] have shown that the yield behavior of PC tested in tension at low strain rateε� and at temperatures from -20 to 145°C can be expressed by the exponential form of the Eyring equation: ST Q A Ln2C T RT α α α σ = ε + �
This last result is in accordance with observations made by Sahn et al. [13].

The corrosion resistance of steels alloys can be affected by adding Al content.
Following the recent outcomes on ODS alloys, the authors developed a new generation of low-cost Fe-Al-Al2O3 based ODS steel which called Fe-Al-O oxide precipitation hardened (OPH) steel.
