| 摘 要： | 研究了２５ＳｉＭｎＭｏＶ钢粒状贝氏体组织和回火过程及其回火组织形态，粒状贝氏体的回火转变主要是（Ｍ－Ａ）小岛的回火转变，包括残余奥氏体转变及马氏体分解。粒状贝氏体经中、高温回火后，在铁素体晶界上存在碳化物偏聚，容易引起组织脆化。 |
| 关 键 词： | 粒状贝氏体 回火 钢 25SiMnMoV钢 热处理 |

| Abstract: | The paper deals with the tempering process of granular bainite in 25SiMnMoV steel as well as the morphology granular bainite mainly that of (M-A) island,including the transformation of retained austenite and the decomposition of martensite brittleness may be caused by carbide accumulation on ferrite grain boundaries,after granular bainite tempered at middle or high temperature. |
| Keywords: | granular bainite tempering (M - A) island |
