摘　　要：通过改变淬火工艺参数研究其对2024铝合金晶间腐蚀及组织性能的影响规律。结果表明,随着淬火转移时间的延长、淬火温度的降低和淬火保温时间的缩短,将影响2024铝合金晶间第二相的形态和分布,增加晶间腐蚀的最大深度;合金在500℃下保温30min淬火,淬火转移时间控制在5s,可保证制品的晶间腐蚀性能满足技术要求。In this paper,the effect of quenching process parameters on intergranular corrosion and microstructure properties of 2024 aluminum alloy is studied.The results show that the morphology and distribution of intergranular second phase will be affected and the maximum depth of intergranular corrosion will be increased with the extension of quenching transfer time,the decrease of quenching temperature and the shortening of quenching holding time.The alloy is held at 500℃for 30min for quenching,and the quenching transfer time is controlled within 5s,which can ensure that the intergranular corrosion properties of the products meet the technical requirements.
