Abstract The recrystallization behaviour and Al3(Sc, Zr) particles were studied by annealing the samples with different deformation ways. Two samples were studied, cold rolling (CR) and equal channel angular pressing (ECAP). The ECAP sample has higher dislocation density, leading to the results that the ECAP sample is recrystallized thoroughly whereas the CR sample is only recrystallized partly. Additionally, the morphology of Al3(Sc, Zr) particles are changed after the recrystallization. Almost all the Al3(Sc, Zr) particles in ECAP sample are incoherent and large, losing pinning effect, but those in the CR sample just grow up a bit and pin the grain boundaries (GBs) strongly.

基于两种不同变形方式的Al-Mg-Mn-Sc-Zr合金再结晶行为

摘要 通过对不同变形方式的试样进行退火，研究了再结晶行为和Al3(Sc,Zr)粒子。研究了两个样品，冷轧 (CR) 和等通道角压 (ECAP)。ECAP样品具有较高的位错密度，导致ECAP样品完全再结晶而CR样品仅部分再结晶的结果。此外，再结晶后 Al3(Sc, Zr) 颗粒的形态发生了变化。ECAP 样品中几乎所有的 Al3(Sc, Zr) 颗粒都是不连贯的和大的，失去钉扎效应，但 CR 样品中的那些只是稍微长大并强烈钉住晶界 (GBs)。
