| 摘 要： | 分析了双相热处理工艺参数对08Mn2Si组织、性能的影响，探讨了其强韧化机理。研究结果表明：08Mn2Si钢丝经双相热处理后可得到板条马氏体与少量铁素体相间分布的细小均匀的双相组织，其屈服强度大幅度提高，同时塑性指标也明显改善，这是固溶强化、位错强化和细晶强化综合作用的结果。

| Abstract: | Tbe influence of dual phase heat treatment on the microstructure and mechanical properties of 08Mn2Si was studied, and the strengthening mechanism was discussed. The results show that fine dual phase microstructure with martensite and a little ferrite can be obtained by proper dual phase heat treatment. The strength and elongation of 08Mn2Si after dual phase heat treatment are improved obviously, which is the result of combination of dislocation strengthening and grain refining strengthening. |
