| Abstract Scope |
In this work Mg-x wt.% Al alloys were produced by high energy ball milling (HEBM) and consolidated using spark plasma sintering. Hardness, microstructure, and phase analysis for the alloys were investigated using Vickers’ micro-indenter, scanning electron microscopy, and X-ray diffraction, respectively. Potentiodynamic polarization and electrochemical impedance spectroscopy studies were done using a potentiostat in 0.1 M NaCl and 0.1 M Na2SO4, respectively, at ambient temperature. The hardness increased with an increase in the Al content even though the grain size increased, which correlates with various strengthening contributions from Al addition. The corrosion behavior improved on Al addition up to 10 wt.% and deteriorated for higher Al content. The corrosion behavior will be discussed based on microstructural changes Present work is valuable in designing the Mg-Al based alloys produced by HEBM with enhanced strength and corrosion resistance. |
