Rapidly solidified(RS)AZ31 magnesium alloy ribbons were made using melt spinning technique.The results show that its microhardness increases with the wheel speed,and after heat treatment,the microhardness of the ribbons produced at 1600 r/min also increases.Rapid solidification leads to reduction of grain size.When the wheel speed reaches 1600 r/min,no Mg17 Al12 phase precipitates,while heat treatment at 200 ℃ leads to precipitation of Mg17 Al12 phase.Al-Mn intermetallic compounds with size no larger than 10 nm appear in as-spun ribbons.The corrosion potential of the as-cast ingots is lower than that of the as-spun ribbons.
