Effect of Rare Earth Y on the Textures of High Purity Aluminum

  • 摘要: 采用晶体取向分布函数(ODF)法研究和分析了在高纯铝中加入微量稀土Y对冷轧形变织构和再结晶立方织构的影响.结果表明:在高纯铝中添加微量Y,可提高铝箔中再结晶立方结构的成分,当w(Y)为0.001 5%时,立方织构很强;但Y添加量的变化不改变冷轧织构类型.作用机理是微量稀土Y与高纯铝中杂质元素可形成FeYAl8、Fe6YAl6、Fe4YAl8、Si1YAl2、Si2YAl2及Cu4YAl8等化合物,这些化合物的形成能净化基体,退火时有效消除了杂质元素,特别是Fe对立方晶核形成和长大的阻碍作用,从而可提高再结晶立方织构成分.
    Abstract: The effect of adding trace rare earth (Yttrium) on cold rolling texture and recrystallization texture of high purity aluminum is investigated and analyzed in detail by means of crystal orientation distribution functions (ODF). The experimental results show that the adding of trace yttrium has not changed the type of cold rolling texture. However, the cube recrystallization texture can be strengthened with the increasing of the content of element Y. The cube texture is the strongest when w(Y) is 0.001 5%. The rare element Y may combine with the other impurities to form metallic compounds, such as FeYAl8, Fe6YAl6, Fe4YAl8, Si1YAl2, Si2YAl2 and Cu4YAl8. When the precipitation of these particles in the matrix is nearly completed and the Fe concentration in the matrix become low, the cube recrystallization texture develops well.
