研究了３００４铝合金经大变形量冷轧后进行退火时的形核行为。结果表明，在３００４铝合金再结晶退火时，主要有亚晶多边化和合并／长大形核以及粗大第二相变形区与晶界形核等形核机制。通过显微组织分析和数学计算，发现再结晶立方取向晶核的形成主要发生在变形基体中的三角晶界、粗大的Ａｌ（Ｆｅ，Ｍｎ）Ｓｉ和（Ｆｅ，Ｍｎ）Ａｌ６第二相（尺寸大于２．５μｍ）周围强烈的晶格畸变区和取向紊乱区以及变形带中具有严格或近似立方取向的亚晶粒等处。
The nucleation behavior of 3004 aluminum alloy after annealing with large deformation and cold rolling was studied. The results show that in the recrystallization annealing of 3004 aluminum alloy, there are mainly nucleation mechanisms such as subgrain multilateralization and coalescence / long nucleation as well as coarse second phase transformation zone and grain boundary nucleation. Through the microstructure analysis and mathematical calculation, it was found that the formation of recrystallized cubic orientated nuclei mainly occurs in the triangular matrix of the deformed matrix, the coarse Al (Fe, Mn) Si and (Fe, Mn) Al6 second phase More than 2.5μm) around the strong lattice distortion and misorientation zone and the deformation zone with strict or approximate cubic orientation subgrains and so on.
