【Abstract】 The properties of low carbon steel can be greatly enhanced when its grain size becomes ultrafine.Approaches to obtain ultrafine grain size for low carbon steel,such as microalloying,electromagnetic field treatment and thermo-mechanical treatment after rolling,are given in this paper.In addition,the mechanism and technologies of ultrafine granulation are also discussed.更多还原
