Abstract
本发明属于有色金属材料技术领域，具体涉及一种高强度耐腐蚀性Al‑Mg‑Si‑Cu‑Zn铝基交叉合金及其制备方法。现有技术中的铝合金存在力学性能和耐腐蚀性难以同时提高等问题。本发明以锌、铜、硅、镁、锰、铬制备铝基交叉合计，且同时满足0.40≤Zn / Cu≤1.00、0.75≤Mg / Si≤1.50、2.60≤(Zn+Cu)*Mg / Si≤5.80；制备该交叉合金时，根据配比进行熔炼，铸造成铸态合金坯料，经双级均匀化热处理后锻造成合金板材，经固溶处理后立即水淬，再进行非等温分阶段时效处理，得到具有高强度、高耐腐蚀性的铝基交叉合金，具有优异的成分兼容性与回收友好性，以及显著的工程应用前景和产业化价值。
