摘　　要：为帮助制造商和客户更好地进行生产过程工艺控制和了解其对应的理论依据,对淬火转移时间与淬火后停放时间对7475铝合金性能和组织的影响进行了研究。研究表明,7475铝合金的力学性能基本不受淬火转移时间(在60 s之内)和淬火后停放时间的影响,其对淬火转移时间和停放时间不敏感的原因在于其淬火后形成的析出相的临界核心相对稳定。In order to help manufacturers and customers better control the production process and understand its corresponding theo⁃retical basis,this paper studied the effects of quenching transfer time and quenching parking time on the properties and microstructure of 7475 aluminum alloy.The results show that the mechanical properties of 7475 aluminum alloy are not affected by quenching trans⁃fer time(within 60 s)and parking time after quenching.The reason for its insensitivity to quenching transfer time and resting time is that the critical core of the precipitated phase formed after quenching is relatively stable.
