Effect of texture evolution on corrosion resistance of AZ80 magnesium alloy subjected to applied force in simulated body fluid

Abstract: The electrochemical corrosion behavior of a rolled AZ80 magnesium alloy after pre-compressive strain along different orientation in a simulated body fluid (SBF) was investigated by immersion test for 48 h. The results showed that the corrosion resistance is related to the crystal texture of the material. The texture evolution induced by plastic deformation changed the corrosion behavior of the magnesium alloy. Slip and twin associated with plastic deformation changed the orientation of crystallographic planes.… Show more

“…sion was previously reported in the literature [52][53][54]. The texture effect on the biocorrosion of the magnesium-based, AZ80, has also been noted in the literature (e.g., [40]). Work [55] reported relatively high corrosion resistance of the orientation (00.2) by comparison with the corrosion test results obtained for a material rolled and then 2.5-h annealed at 340 °C and another, additionally compressed, to a strain of 9%.…”

“…On the other hand, twins of system can increase the corrosion resistance. This is related to the high oxidation activity of atoms in the twin plane as compared with atoms in the densely packed basis plane [ 52 , 53 ], which allows for the easier formation of the oxide film or reduced effects of corrosion anisotropy in misoriented areas in the materials. Twin boundaries are fully coherent and have a lower inter-phase energy than some non-coherent grain boundaries.…”

“…Moreover, dislocations distort the lattice, and atoms in the distorted lattice are more active than those in normal lattice and are susceptible to corrosion [63]. Therefore, a high dislocation density can decrease the corrosion resistance of alloys through corrosion preferably at the outcrop of dislocations [64,65].…”
