Effect of Y addition on microstructure, tensile properties, and corrosion behavior of high-speed-extruded Mg–5Bi–3Al alloy

This study investigates the effect of Y addition on the microstructure, tensile properties, and corrosion behavior of high-speed-extruded Mg–5Bi–3Al (BA53) alloy. Y-free BA53 and Y-containing BAW53 x alloys ( x = 0.2, 0.5, and 1.0 wt.%) are extruded at a die-exit speed of 67 m/mi...

Simultaneous enhancement of hardness and corrosion resistance in liquid-metal-dealloyed Mg–Ti composites via short-time Al-melt treatment

This study presents a short-time reactive Al-melt treatment that simultaneously enhances hardness and corrosion resistance in liquid-metal-dealloyed Mg–Ti composites. A three-dimensional bicontinuous Mg–Ti composite is first fabricated by immersing a Ti 30 Cu 70 precursor in a pu...
