摘要
锆具有抗辐照、耐腐蚀、热膨胀系数小和密度低等优异性能。然而,纯锆的强度较低,限制了其在航空航天领域的广泛应用。本文从成分设计优化、组织性能之间的关系和强化机制等方面综述了团队近十几年在高强韧锆合金方面的研究进展,并阐述了所开发的新型高强韧锆合金在航空航天领域的应用。
Zirconium has excellent properties such as radiation resistance,corrosion resistance,low thermal expansion coefficient and low density.However,the low strength of pure zirconium limits its widespread application in the aerospace field.In this paper,the progress of high strength and toughness zirconium alloys developed by our team in recent ten years is reviewed from the aspects of composition design optimization,relationship between microstructure and properties and strengthening mechanisms,and the application of the developed new high strength and toughness zirconium alloys in aerospace field is described.
