Abstract Nd was added to AM50 magnesium alloys to study the microstructure, mechanical properties and creep resistance properties. The specimens were heated at 420℃ for 12 h followed by quenching, and the results show that addition of small amount of Nd to AM50 magnesium alloys resulted in the refinement of grain.The RT trengthening mechanism of alloys containing Nd was mainly from the fine grain strengthening. Nd in AM50 exists in the form of Al$_{11}$Nd$_{3}$ that is thermal stable phase. Due to the existing of Al$_{11}$Nd$_{3}$, the steady state creep rate decreased greatly at the temperature 200℃ and the elevated temperature mechanical property (150℃)
were increased.
