Effects of Different Stretching Routes on Microstructure and Mechanical Properties of AZ31B Magnesium Alloy Sheets

Effects of Deformation Texture and Twins on the Corrosion Resistance of Rolled AZ31 Mg Alloy Under 5% Uniaxial Compression

“…The (0001) plane (1.13 9 10 19 atoms/m 2 ) possesses the higher atomic density than (11-20) (6.94 9 10 18 atoms/m 2 ) and (10-10) (5.99 9 10 18 atoms/ m 2 ) planes [24]. But it is known that the surface of higher atomic density has lower surface energy, and according to the model proposed by Fu et al [36], the surface energy values of (0001), and (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) surfaces of Mg alloys are 1.808, 1.868 and 2.156 eV/nm 2 , respectively, which can be transformed into 1.54 9 10 4 , 3.04 9 10 4 and 2.99 9 10 4 J/mol, respectively. According to previous literature, a higher energy surface of metal is beneficial to the adsorption of hydrogen ions and thus promoting the hydrogen evolution reaction [5,37,38].…”

“…Moreover, Ascencio et al [8,9] investigated the influence of electrolyte renewal and immersion time on the corrosion of Mg alloy in simulated body fluid (SBF). On the other hand, the microstructure and texture evolution of AZ31 during uniaxial loading along different directions have been investigated in early studies [10][11][12][13][14][15][16][17]. Choi et al [10] studied the orientation of grains and twin bands in the AZ31 Mg alloy under uniaxial compression, during which twins occurred by grains rotation and led to various deformation textures.…”

Magnesium alloys: a review of applications

“…In automotive applications, it shows better performance due to its stiffness, high vibrational absorption capacity and excellent cutting performance. [8][9][10][11][12][13][14][15][16][17][18] But in practical applications, while it is subjected to cyclic structural component usually affected by corrosion attack, this leads to corrosion fatigue failure under non-corrosive environments, while fatigue failure occurs at stress variations below the designed values. 19,20 But the fatigue strength of Mg alloys is very good in the air, it is almost satisfactory in industrial standards.…”

Mechanical and corrosion behaviour of in situ intermetallic phases reinforced Mg-based glass composite

“…Magnesium alloys have great potential use as functional and structural materials, due to their unique properties, such as low density, high damping capacity and excellent electromagnetic shielding abilities. However, the poor corrosion resistance and low strength severely limit their wide applications [1][2][3].…”
