| 图2 贝/马复相(LB/M)组织600 ℃回火硬度随下贝氏体(LB)体积分数的变化，及回火时间延长至100 h时单一马氏体(100%M)、贝/马复相(56%M + 44%LB)和单一下贝氏体(100%LB)回火硬度的变化 |
| Fig.2 Hardness (H) variations against the volume fraction of lower bainite (LB) in the lower bainite/martensite (LB/M) microstructures on tempering at 600 oC up to 16 h (a), and hardness variations in the singular martensite (100%M), LB/M (56%M + 44%LB), and singular lower bainite (100%LB) microstructures upon temp-ering at 600 oC up to 100 h (b) |
