隨著資源、能源和環境壓力日益加大,超高強度鋼的開發越來越受到世界各國的極大重視。傳統的超高強度鋼大都是依賴提高碳含量或合金元素含量而獲得較高強度的馬氏體或貝氏體鋼,此種鋼存在著焊接性能差、塑韌性低、鋼材尺寸受限制和成本昂貴等問題,嚴重制約了經濟的快速發展和現代國防的建設,因此,開發綜合性能良好、成本低廉的新型超高強度鋼刻不容緩。結合當前納米科技的發展,介紹了新型納米強化超高強度鋼的設計理念,闡述了以納米相析出強化為主、多種強化方式結合的強韌化理論,并總結了納米析出強化超高強度鋼在合金設計和工藝優化等方面的初步研究進展,最后探討了新型納米強化超高強度鋼亟待解決的問題。

In view of the limited material resources and energy supply available together with serious environment impact concerns at the present time, the development of ultra high strength steels has attracted a great deal of attentions from various countries in the world. As we know, most traditional high strength steels have been developed based on martensitic and bainitic structures with high levels of carbon or high alloy additions. However, these alloys are facing many severe problems, including poor weldability, low ductility and toughness, fabrication size limitation, as well as high production cost, all of these resulting in slowdown of the economic and nationaldefense developments in China.
