本文研究了15CrMnMoV,18Mn2CrMoB,18Cr2Ni4W,30CrMnSi,30CrMnSiNi2及40CrMnSiMoV等结构钢获得贝氏体组织后,于一系列温度回火时的组织与性能变化,重点探讨了回火贝氏体脆性的表现行为和形成机理。
The variations of structures and properties of some structural steelssubjected to tempering at a series of temperature after austempering or continuouscooling at certain rates, have been investigated. Based on the experimental results,the behavior and mechanism of the tempered bainite embrittlement have been dis-cussed.
