叙述了“新一代钢铁材料”项目背景。分析了基于经济和技术观点的项目研究必要性。重点研究为发展新一代钢铁材料的4个关键科学问题:微米和亚微米组织的形成基础理论、钢中高洁净度的基本规律、非平衡态冶金和在高纯细晶条件下的微合金化理论。将要开发3类新钢铁材料的原型钢:现有屈服强度为200MPa的碳素薄板和长形材,其强度提高到400MPa级;现有屈服强度为400MPa级的微合金钢,或许强度增加一倍,或许使用寿命提高一倍;现有拉伸强度为800MPa的合金结构钢强度将提高到1 500MPa级。所有这些类型钢的开发都要考虑社会发展和经济效益。本文还报告了该项目第一年度的一些进展。
Describes the “new generation of steel materials” project background. Analysis of the project based on economic and technical point of view of the need for research. Focus on the development of a new generation of steel materials for the four key scientific issues: the formation of micron and sub-micron microstructure theory, the basic rules of high cleanliness of steel, non-equilibrium metallurgy and micro-alloying under high-purity fine grain theory . There are three types of prototype steels to be developed for new ferrous materials: existing carbon sheets and plates with a yield strength of 200 MPa and strength up to 400 MPa; existing microalloyed steels with a yield strength of 400 MPa may double in strength , Perhaps doubling the service life; the existing tensile strength of 800MPa alloy structural steel will be increased to 1,500MPa level. All these types of steel development must take into account social development and economic benefits. This article also reports some progress in the first year of the project.
