Examining deformed states during elevated temperatures, spd of Al-Mg-Si alloys
seems to have not implicitly been carried out [5].
Vaseghi et al. [8] and Semiatin et al. [9] have shown that the plastic deformation in ecap is not completely homogenous.
Jinxu et al. [11] showed Tungsten heavy alloys are able to resist to asb due to their high strain rate sensitivity.
Xue et al. [14] and Cho et al. [15] have reported the shear band formation in the foregoing behavior for the stainless steel and HY-100, respectively.

The bond performance of 82 concrete specimens with FRP bars are investigated by GAO et al. [1], and the development length and modified coefficient are presented.
Guadagnini et al [14] investigated the shear behavior of 6 beams with FRP bars.
El-Sayed et al [15] compared five methods, including ACI 440.1R-06, CSA-S806-02, ISIS-M03-07, the British Institution of Structural Engineers guidelines and mendation of the Japan Society of Civil Engineers.
Xu et al. [24] did research on bending resistance of reinforced concrete beam strengthened with near-surface mounted FRP bars.

Introduction
According to Fe-Al equilibrium phase diagram [1], three types of non-stoichiometric intermetallic compounds (FeAl2, Fe2Al5 and FeAl3) might appear in the Al-rich region.
The nominal compositions of these alloys were Al-Fe33.28 at% and Al-Fe28.45 at% respectively.
XRD patterns of the Al-Fe33at% as-cast and ball milled samples.
XRD patterns of the Al-Fe28.45at% as-cast and ball milled samples.

Fletcher et al. studied the effect of heat on geopolymer with various Si/Al ratios ranging from 0.5 to 300 [5].
The result is in agreement with that reported earlier by Temuujin et al. [10] and Khan et al. [11].

Fly ash was used as the source of Al2O3 in the first set of two mixtures (FA-1, FA-2), whereas reactive alumina was used as the source of Al2O3 in the second set of two mixtures (AL-1, AL-2).
As a result, mixtures FA-1 and AL-1 have the same amount of magnesium, silicon and aluminium oxides as well as mixture FA-2 has the same amount of these oxides as AL-2.
FA-1 and AL-1 mixtures were designed to contain 10 wt.% of spinel and 15 wt.% of spinel in mixtures FA-2 and RA-2.
