The Properties and Structure Stability of Martensite-Bainite Dual Phase Structure in Bearing Steel
The Martensite-Bainite(M/B)dual phase structure has excellent combined processing properties which can be applied to the bearing steel.Frequently,the service conditions of rolling mill bearings are so harsh that the organization and performance of the bearing materials may change during the using process.The study of structural stability of martensite-bainite dual phase structure is extremely essential.This paper determined the superiority of Martensite-Bainite(M/B) dual phase structure applied to G55SiMoV by contrasting the properties of single martensite and M/B dual phase structure.temper resistance is discussed by testing the change of organization and performance after temper.The results show that the combination property of the M/B dual phase structure are better than the martensitic structure.The G55SiMoV steel with martensite-bainite dual phase structure has a greater temperature range to ensure the tempering stability.
