中文摘要：研究了铸造镁合金AZ91D在施加磁场时效前后微观组织及力学性能的变化。结果表明，在交流磁场作用下时效时，AZ91D镁合金的微观组织发生变化，β相增多且分布均匀，耐腐蚀性能略有提高。
英文摘要：The changes of microstructure and mechanical properties of AZ91D alloy as-cast before and after aging in magnetic field were investigated. The results show that under aging in AC magnetic field, the microstructure of the AZ91D alloy changes, β-phase increases and its distribution becomes uniform, the corrosion resistance of the material slightly increases.
