Effects of Deformation Texture and Grain Size on Corrosion Behavior of Mg–3Al–1Zn Alloy Sheets

[Image: see text] Effects of deformation texture and grain size on mechanical properties and corrosion behavior of the Mg–3Al–1Zn (AZ31) alloys were systematically investigated. The results revealed that the ultimate tensile strength (UTS) and fracture elongation (FE) significantly increased from 23...

description [Image: see text] Effects of deformation texture and grain size on mechanical properties and corrosion behavior of the Mg–3Al–1Zn (AZ31) alloys were systematically investigated. The results revealed that the ultimate tensile strength (UTS) and fracture elongation (FE) significantly increased from 232 to 273 MPa and 12.5 to 26.4%, respectively. According to the immersion and electrochemical measurements, the results indicated that the corrosion resistance of the alloy was improved obviously. Via electron backscattered diffraction (EBSD), corrosion morphology showed that the propagation of local pitting corrosion was suppressed, which is ascribed to grain refinement, higher texture intensity, and lower dislocation density after rolling and subsequent annealing.
