“…In order to cater for the developing demand of aerospace, it often requires to modify alloy composition, add some different grain refining elements [1][2][3], or achieve the fine microstructures by extensive deformation [4][5][6], such as forging, accumulative rolling, compressed-torsion, cyclic extrusion pressing and so on. Equal-channel angular pressing (ECAP) is preferred to produce ultrafine-grained bulk samples in a fully dense condition without changing the cross-sectional dimensions of the samples.…”

“…Figures (1) and ( 2) depict the X-ray diffraction patterns of alloys A and B, respectively, as the figure depicts the presence of four peaks for each alloy, indicating that it is polycrystalline (Hexagonal , cubic) for alloy A and (Hexagonal , Anorthic , cubic) for alloy B , and after matching the measured XRD examination values with the international standard cards (JCPDS), the phases whose characteristics were deduced in Tables (2) and (3) for alloy A and B, respectively. The degree of crystallinity for alloys A and B was estimated to be (65.25) and (68.45), respectively, implying an increase in the regular arrangement of the atoms within the crystal structure, resulting in an increase in the X-rays reflected from the crystal levels and thus the rise of Bragg's peaks [11] .…”

Due to the importance of these alloys in the manufacture of aircraft, coatings, radiation shields, and electronic circuits, the study’s objectives include investigating previously unstudied structural properties of some aluminum alloys, alloy A (Al-Zn-Mg-Ti) and alloy B (Al-Zn-Mg-Mn) were prepared using the casting method, and their structural properties were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques (granular size and theoretical density). The results of analyzing the X-ray diffraction data and determining the phases formed on the two alloys after matching them with the international standard cards (JCPDS) revealed that it is polycrystalline, with structures (cubic and hexagonal) on alloy A and structures (cube, hexagonal, and anorthic) on alloy B. The results revealed that the average grain size estimated by the Debye-Scherer method is less than that estimated by the Williamson-Hall method, and that the grain size of alloy A is less than that of alloy B due to the presence of titanium in alloy A’s composition, which works to reduce particle size. The theoretical density of Alloy A and B that was used in X-ray diffraction was calculated. SEM analysis of the spherical shape of the grains on the surfaces of alloys A and B revealed that the average grain size on the surface of alloy A is smaller than on the surface of alloy B, which is consistent with the results of XRD analyses.

“…existing in BM. These dispersoids have been thought can pin dislocations, subgrain boundaries, grain boundaries strongly, and improve recrystallization temperature dramatically [11,13,31]. The average grain size of HAZ and BM are 9.18 lm and 8.39 lm respectively according to statistics of grains with more than 2°misorientations.…”
