摘要：

The magnesium alloy is prone to burn during die-casting, which limits its applications severely, so the effect of adding rare earth (RE) on the ignition-proof of AZ91D Mg alloy is studied. The results indicate that the addition of mischmetal RE elements has a remarkable influence on the ignition-proof property of the magnesium alloy. It is found that the ignition temperature of the magnesium alloy can be greatly raised by adding a proper amount of RE. When the amount is 0.1wt%, the ignition temperature reaches 877 degrees C which is 206 degrees C higher than that of AZ91D without RE and the mechanical properties of the alloy are also improved. However, the amount of RE must be properly controlled because too much RE would induce grain coarsening and reduce the mechanical properties.
