超细晶钢铁材料研究进展综述

Research Progress on Ultra-fine Grained Steel Materials

本文介绍了几种常用的晶粒细化方法，包括微合金细化法、电磁场细化法、纳米析出相细化法、应变诱导相变和形变强化相变，分析了超细晶材料在开发和应用中存在的问题，为钢铁材料晶粒细化的研究及实际应用提供参考。

Such normal grain refining methods as micro-alloy refining method, electro- magnetic field refining method, nanometer-sized precipitation refining method, strain in- duced transformation and deformation enhanced transformation were introduced. The exist- ing problems in development and applications of ultra-fine grained steel materials with grain refinement were analyzed so that some references for development and applications of grain refining methods for steel materials in practice were offered.
