“…The alternating ND and TD deformations also gave rise to a unique spilt texture of the caliber-rolled Mg alloys. Such a texture has been reported in other Mg alloys subjected to caliber rolling, such as AZ31 [15] and ZK60 [17]. These results suggest that the caliber rolling process, rather than the alloying compositions, induced the split basal texture in the investigated Mg alloys.…”

“…Research on caliber-rolled Mg alloys has been limited compared to that on caliber-rolled ferrous alloys. Moreover, these studies have focused primarily on commercial AZ31 Mg alloys [12][13][14][15][16]. Only a few studies have recently investigated the effect of caliber rolling on other Mg alloys, such as ZK60 alloy [17,18], Mg-Mn alloy [19], and Mg-Al compound casting [20].…”

Multi-pass caliber rolling has proven its vast potential for ultrafine-scale grain refinement and mass production of various metals. Nevertheless, the studies related to Mg alloys have primarily focused only on a few commercial materials, such as AZ31 and ZK60 Mg alloys. This is the first study to investigate caliber-rolled Mg–1Sn (TM10) and Mg–1Sn–1Mn (TM11) alloys. Specifically, this work aims to elucidate the microstructural characteristics of these alloys, including grain refinement, recrystallization, and texture development. Such features were discussed from the viewpoints of alloying effects (i.e., Sn and Mn) and mechanical effects (i.e., caliber-rolling strains). The combination of the addition of Mn and high-redundant strain results in effective grain refinement of the caliber-rolled TM11 Mg alloys. In addition, both TM10 and TM11 Mg alloys exhibit a unique split basal texture, wherein the basal poles are tilted in the plane normal to the rolling direction.

“…The ET0°anode has a traditional strong basal texture, which is consistent with the commonly reported in extruded AZ31 sheet. The result implies that the ET0°anode mainly consists of the (0002) orientated grains, while the prismatic orientated grains such as the grain A with (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) II. The corrosion current density (i corr ) can be obtained using Tafel fitting of the cathodic branch.…”

“…The ET90°anode has a more uniform dissolution than the ET0°anode, leading to its higher anodic efficiency than the ET0°anode. It is well known that the (0002) orientated grain with higher binding energy dissolve slowly during the discharge process, whereas the (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) and (10-10) orientated grains with lower binding energy dissolve quickly. 5,11,35 In this work, the (10-10) and (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) oriented grains suffer more severe attack than the (0002) oriented grains (seen Figs.…”

“…Herein, a low-cost, environmentally friendly, and high-performance Mg alloy anode material should be further developed. Of those, AZ31 (Mg-3Al-1Zn, in wt.%) alloy, a traditional light-weight engineering material, [14][15][16][17][18][19][20][21][22][23][24] has been widely used in automobile parts, aircraft wheel hubs, engine housing, and communication equipment in recent years. 14 Accordingly, the researches on improving the mechanical property, 15,25 formability property, 16,17 and corrosion resistance 14,[26][27][28][29] of AZ31 alloy have been widely researched and a series of advances have been made.…”

Here, four representative Mg-3Al-1Zn (AZ31) anodes with different texture characteristics, i.e., ET0°, ET30°, ET60°, and ET90°, are assembled as the anodes for Mg-air batteries. The correlation between texture and discharge products and the influences of texture and discharge products on the discharge performance are studied. The results show that the discharge performance of the four anodes follows the order: ET90°> ET60°> ET30°> ET0°. The improved discharge performance is related to the two aspects: (i) the discharge activities of the (11-20)/(10-10) orientated grains are higher than those of the (0002) orientated grains, (ii) the discharge products formed on the (11-20)/(10-10) surface are more easily to fall off than those formed on the (0002) surface.

Mg–6xZn–xY (x = 0.8, 5, and 7 wt%) alloys containing an icosahedral quasicrystal phase (I‐phase) are synthesized, and the effects of Y doping on the microstructure and mechanical properties of the Mg matrix and I‐phase are investigated. The results show that as the Y content increases, the I‐phase content gradually increases, with the distribution of the I‐phase changing from a discontinuous to a continuous network and lamellar structures. Additionally, the eutectic structure (α‐Mg + I‐phase) in the alloys gradually increases, while the Mg matrix area decreases. The tensile strength of the as‐cast alloy initially increases and then decreases, reaching a maximum value at Y = 5. Heat treatment of the Mg–30Zn–5Y alloy reveals an optimal solid solution temperature of 320 °C, resulting in a tensile strength of 175.09 MPa and quasicleavage fracture characteristics. The maximum tensile strength of the alloy is achieved when the I‐phase distribution is continuous and the porosity of the Mg matrix is ≈66%. These results provide guidance for the microstructural design of I‐phase‐reinforced Mg alloys with rare earth elements to enhance their mechanical properties.
