摘要 利用三维取向分布函数(ODF)和透射电镜(TEM)等方法研究了电场退火对冷轧3104铝合金板材再结晶、第二相粒子和再结晶织构的影响。结果表明:电场退火具有抑制铝合金板再结晶形核和长大的作用,但并未改变其再结晶形成机制;促进了第二相粒子MnAl6长大;有利于提高立方织构({001}〈100〉)的强度,同时降低了某些轧制织构的强度。根据Gibbs Thomson理论,探讨了电场退火时3104铝合金板再结晶及立方织构形成机制。 The effects of electric field on microstructure, precipitation and recrystallization texture of cold rolled 3104 aluminum alloy sheets were investigated by X-ray-ODF analysis combined with TEM morphology. The cold rolled 3104 aluminum alloy sheets were treated at different temperatures for 90 min with conventional annealing and electric field annealing, respectively. The result shows that the electric field annealing retards the recovery and recrystallization processes, reduces the mean grain size, and increases the size of MnAl_6 and enhances cube texture. According to Gibbs-Thomsons theory, such effects are attributed to the fact that the electric field decreases the driving force of recrystallization, and then hinders the nucleation and grain-growth. As the S oriented grains have relatively high storage energy, they have strong preference to recrystallization. As a result, the cube texture is enhanced.
