镁合金作为最轻的结构材料,在汽车、航空航天等领域的应用显示出巨大的节能减排效果。特别是,含锆镁合金(不含铝)表现出高强度和高温使用价值。 Zr 是最强大的晶粒细化剂,可为镁合金提供细小的晶粒尺寸、均匀的微观结构和机械性能以及加工成型性。鉴于Zr合金化的重要性,本文系统总结了Zr对镁合金晶粒细化作用的最新研究进展。综述了Zr的合金化过程、Zr的晶粒细化机理、影响Zr晶粒细化效果的因素以及提高Zr晶粒细化效率的方法等要点。本文为研究人员和工程师提供了Zr对镁合金晶粒细化作用的全面认识。
As the lightest structural materials, Mg alloys show great effectiveness at energy saving and emission reduction when applied in the automotive and aerospace fields. In particular, Zr-bearing Mg alloys (non-Al containing) exhibit high strengths and elevated-temperature usage values. Zr is the most powerful grain refiner, and it provides fine grain sizes, uniformities in microstructural and mechanical properties and processing formability for Mg alloys. Due to the importance of Zr alloying, this review paper systematically summarizes the latest research progress in the grain refinement effects of Zr on Mg alloys. The main points are reviewed, including the alloying process of Zr, the grain refinement mechanism of Zr, factors affecting the grain refinement effects of Zr, and methods improving grain refinement efficiency of Zr. This paper provides a comprehensive understating of grain refinement effects of Zr on Mg alloys for the researchers and engineers.
