摘要
综述了目前钢铁材料的各种晶粒细化方法、原理及其研究动态,展望了钢铁材料晶粒细化技术的研究前景,以期对新一代钢铁材料的研究和开发提供理论指导。分析认为今后钢铁晶粒超细化技术的研究方向主要有2个方面:一是继续深入讨论和探索晶粒超细化机理以及超细晶粒材料结构与性能的关系;二是开发适宜于工业化生产的钢铁晶粒超细化技术。
The grain refinement methods, its principles and its present research development are summarized,and the prospect of the iron and steels grain refinement technique is also forecasted. The purpose of the present work is to afford theoretical guideline for the research and development of the new generation iron and steel materials. It＇s believed that the following research directions may be the future exploring directions of the iron and steel materials grain refinement.： one is to investigate the grain refinement mechanisms and the relationship between the properties and the microstructures of the uttrafine-grained materials, and the other is to develop new grain refinement technique that could be industrially applied.
