Ausforming Followed by Below-Ms Austempering of Low-carbon Si-rich Bainitic Steel

摘要：

　　The microstructure and tensile properties of a low-carbon high-Si steel prepared by a new thermo-mechanical process,i.e.ausforming followed by below-Ms austempering,have been studied.The results show that the new thermo-mechanical process reduces effectively the bainitic structure and,meanwhile,increases significantly the total amount of retained austenite,as compared with the non-ausforming process.Consequently,the samples prepared by the combined process show superior tensile properties,i.e.significantly-improved yield and tensile strengths with admirable ductility comparable to the non-ausformed sample.
