摘要(Abstract)：

采用光学显微镜、扫描电镜、透射电镜和电子万能试验机等研究了脉冲磁场时效工艺对6082铝合金组织和力学性能的影响。结果表明：在6082铝合金时效过程中施加脉冲磁场，能够提高扩散通量及原子振动频率，使合金在时效早期形成更多GP区，这些GP区在后续时效过程中形成β″相，并且由于原子扩散加快，形成β″相的速度远大于常规时效，使得6082铝合金基体中β″相数量增加，β′相尺寸缩小；经175℃脉冲磁场时效180 min后，6082铝合金的力学性能最优，其抗拉强度为348.41 MPa、屈服强度为300 MPa、伸长率为17%,相比常规时效工艺，力学性能更好，且时效时间缩短了62.5%。
