The effects of addition of Mn, Ti and Cr on microstructures and properties of Al-Zn-Mg-Cu-Zr alloys were investigated by performing room-temperature tensile test, intergranular corrosion test and electrochemical corrosion test, combined with microstructural characterization techniques such as optical microscopy, scanning electron microscopy and transmission electron microscopy. The results demonstrate that additions of Mn, Ti and Cr can effectively inhibit alloy recrystallization and promote fine and dispersed precipitation of η′ phase. This leads to grain boundary precipitates in a continuous chain-like distribution changed to be discontinuously distributed in a line. Consequently, the yield strength, tensile strength and elongation of the alloys are improved, and the depth of intergranular corrosion and the corrosion current density are reduced; meanwhile the polarization resistance is increased. It is shown that both mechanical properties and corrosion resistance of alloys are significantly enhanced.

通过室温拉伸、晶间腐蚀和电化学腐蚀等实验，结合金相显微镜、扫描电镜、透射电镜等表征手段研究复合添加Mn、Ti、Cr对Al-Zn-Mg-Cu-Zr合金组织和性能的影响。结果表明，复合添加Mn、Ti、Cr可以抑制合金再结晶，促进η′相细小弥散析出，使晶界析出相从链状连续分布变为条状不连续分布，从而提高合金屈服强度、抗拉强度和延伸率，减小晶间腐蚀深度，降低腐蚀电流密度，增加极化电阻，使合金力学性能和抗腐蚀性能得到增强。
