Enhanced mechanical behavior and corrosion resistance of AZ31 magnesium alloy through a novel solid-phase processing

In this work, a novel solid-phase processing; namely, shear assisted processing and extrusion (ShAPE) was used to modify the microstructure of AZ31 magnesium alloy, which simultaneously improved corrosion resistance along with mechanical properties compared wrought alloys. A noble breakdown potential, higher polarization resistance, smaller film thickness after immersion observed ShAPE processing. The processed alloy attributed grain refinement, homogenized distribution second phases, low residual strain in matrix. Similarly, tilted basal texture direction contributed towards enhanced ductility eliminated tension-compression asymmetry.
