研究Zr添加对Al?Mn?Si?Zn合金显微组织、力学性能及电化学性能的影响。透射电镜观察表明，Zr合金化可使退火态合金中的析出相更加细小、弥散，但是对模拟钎焊态合金的影响较弱。拉伸实验结果表明，添加Zr 能够显著提高退火态合金的力学性能，但是对模拟钎焊态合金影响不大。电化学实验结果则表明，Zr 元素的添加可降低退火态合金的抗腐蚀性能，但是对模拟钎焊态合金的影响不大。

Effects of Zr addition on the microstructure, mechanical and electrochemical properties of Al?Mn?Si?Zn alloy were investigated. Transmission electron microscopy (TEM) observations reveal that, in as-annealled state, the precipitates in the Zr-containing alloy are finer and more dispersive than those in the Zr-free alloy. Whereas, in simulated brazing state, a weaker precipitation is found in the Zr-containing alloy. Tensile testing results indicate that, with Zr additon, comprehensive mechanical properties of the as-annealed alloys could be significantly improved but weakened for the simulated brazing alloy. Electrochemical testing results reveal that, with Zr addition, the corrosion resistance of the as-annealed alloy decreases. However, after the simulated brazing treatment, such a negative effect of Zr element on the corrosion behavior of the alloy could be negligible.
