提出制备含s.的a.−Cu−Li−Mg−Zr基合金带材的工艺方案。即先采用双辊铸轧技术制备近净形状的3 mm厚带材,再对其进行均匀化/固溶处理。研究两种a.−Cu−Li−Mg−Zr基双辊铸轧合金,其中一种添加质量分数为0.17%的s.,另一种未添加s.。两种合金均先在300℃下退火30 min,然后在450℃下退火30 min以及530℃下退火30 min,随后进行室温水淬。前两段退火后组织中生成了细小、弥散的a._(3)Zr/a._(3)(s.,Zr)颗粒。最后的退火步骤起到了均匀化/固溶处理的作用。双辊铸轧材料的细小晶粒结构使含有主要合金元素的原始颗粒在较短的退火时间内溶解。缩短保温时间可以限制表面层中Li的耗尽和a._(3)Zr/a._(3)(s.,Zr)弥散相的明显粗化。铸态含s.材料已经具有明显细小的晶粒结构,而经均匀化/固溶处理后生成的a._(3)(s.,Zr)弥散相抑制了晶粒在高温下发生粗化。在后续180℃下时效处理后,形成了θʹ(a._(2)Cu)、T1(a._(2)CuLi)和s.(a._(2)CuMg)强化相。在峰值时效状态下,屈服强度提高了200 MPa.这一数值与类似直接冷却铸造材料的相当,从而证实了所提方案的合理性。
