Paper Title:
Rapidly Solidified AZ31 Magnesium Alloy Ribbons Used in Rechargeable Batteries
  Abstract

Better properties of magnesium make it a natural choice for use as an anode material in rechargeable batteries. However, the magnesium alloy thin sheets used in rechargeable batteries were produced by ingot casting and rolling. That technology was so complex and the cost was high. Rapidly solidification by melt spinning is an effect way to solve that problem. In this paper, the technology of rapidly solidified (RS) ribbons in Mg-3%Al-1%Zn-0.2%Mn alloy has been investigated using melt spinning technique. The effect of wheel speed on thickness and microhardness of the ribbons is presented. Microhardness is found to increase with the wheel speed. Rapidly solidification leads to small grains (1~2 µm). The plasticity of the ribbons was well. The quantity of Mg17Al12 decreases with the increase in wheel speed. When the wheel speed reaches 1600 rpm, no Mg17Al12 phase precipitates. As the increase of the wheel speed, the corrosion resistance of the ribbons changes better.
