Abstract Scope |
An increase in demand for high-strength and corrosion-resistant magnesium alloys in transportation sectors has driven the development of new processing techniques. Towards this, in this work, cast and extruded ZK60 magnesium alloys were processed using a novel solid-state process i.e., Shear Assisted Processing and Extrusion (ShAPE). Processing-induced microstructure were characterized using Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) techniques, which revealed an extensive refinement in grain size, distribution of solutes (Zn and Zr) and second phases, and overall texture. Comparative corrosion analysis of ShAPE and feedstock alloys was performed using various electrochemical measurements such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and atomic emission spectroelectrochemistry analysis (AESCE) that indicate an improvement in corrosion resistance with ShAPE processing for cast feedstock but not for extruded ZK60. Post-corrosion microstructures were analyzed to elucidate the underlying corrosion mechanism. |
