- 摘要:
- 由于5000系铝合金具有良好的拉伸力学性能和成形性,被用作汽车内衬板以及形状复杂的结构件。与其它传统变质剂相比,富铈稀土在铝合金改性方面不仅对铝合金晶粒起到细化作用还能改善合金组织中第二相形貌、大小以及分布。综述了5000系铝合金的特点和研究进展,总结了稀土在铝合金中的作用,重点分析了富铈稀土对5000系铝合金的强化机制。
Because 5000 series aluminum alloy has good tensile mechanical properties and formability,it is used as automobile lining plate and complex structural parts.Compared with other traditional modifiers,Ce-rich rare earth(RE)can not only refine the grain of aluminum alloy,but also improve the morphology,size and distribution of the second phase in the alloy structure.The characteristics and research progress of 5000 series aluminum alloy were reviewed,the role of rare earth in aluminum alloy was summarized,and the strengthening mechanism of Ce-rich rare earth on 5000 series aluminum alloy was analyzed emphatically.
