摘要

镁合金在室温下的变形性能较差，在变形过程中施加电脉冲电流可提高塑性成形能力。本研究通过改变脉冲输出电压对 AZ91D 镁合金试样进行了电脉冲轧制。结果表明，输出电压为 300 V 时，表面质量最好，β-Mg17Al12 相的含量最低（8.4%）。EBSD 测试显示，脉冲输出电压为 300 V 时，{0002}和{100}上的织构强度最低，孪晶增强最大。输出电压为 300 V 时，最大拉伸强度为 165 兆帕，输出电压为 200 V 时，最大伸长率为 4.1%。

EFFECT OF OUTPUT VOLTAGE ON AN AZ91D MAGNESIUM ALLOY ROLLED USING AN ELECTRIC PULSE TREATMENT

Magnesium alloys have poor deformation properties at room temperature, and the application of an electric pulse current during deformation can improve the plastic-forming ability. In this study, the electric pulse rolling of AZ91D magnesium alloy specimens has been examined by changing the pulse output voltage. The results demonstrate that the best surface quality and lowest content (8.4 %) of the β-Mg17Al12 phase are achieved at an output voltage of 300 V. EBSD tests have revealed the lowest weave strength on {0002} and {100} at a pulse output voltage of 300 V, as well as the greatest enhancement of twinning. The maximum tensile strength was 165 MPa at an output voltage of 300 V, with a maximum elongation of 4.1 % at an output voltage of 200 V.
