摘要(Abstract)：

研究了脉冲磁场处理工艺参数(脉冲电压和脉冲频率)对铸态Zn-3Cu合金凝固组织及性能的影响。结果表明：脉冲磁场可以有效细化Zn-3Cu合金的凝固组织；随着脉冲电压在0～300 V范围内增加，Zn-3Cu合金的晶粒尺寸逐渐减小；随着脉冲频率在0～10 Hz范围内增加，合金的晶粒尺寸先增大后减小再增大，第二相(CuZn_5)尺寸先减小后增大，当脉冲频率为5 Hz时，合金凝固组织细化效果最佳。脉冲磁场可以提高合金的力学性能和耐蚀性能，当脉冲电压为300 V、脉冲频率为5 Hz时，合金的力学性能和耐蚀性能最好，其抗拉强度为106.05 MPa,伸长率为7.14%,与未经磁场处理的合金相比，分别提高了37.9%和32.7%。
