- 摘要:
- 综述了微量钪对铝合金的显微组织和性能影响的研究现状。 Sc 可以细化铝合金晶粒、抑制再结晶，对其力
学性能、焊接性能和耐蚀性能的提高均有重要的影响。 结合国内外研究，对 Sc 改性铝合金的研究和未来应用提出了一
些看法。
The research status of influence of scandium on microstructure and properties of aluminum alloy was reviewed. Sc can refine the grain size of aluminum alloy and inhibit recrystallization, which had an important influence on the improvement of mechanical properties, welding properties and corrosion resistance. Combined with the research at home and abroad, the research and future application of Sc modified aluminum alloy are prospected.
