| 摘 要： | 本文通过对不同成分的锰－硼钢的等温转变曲线的测试分析．讨论了锰、硼的单独作 用及锰－硼交互作用对转变曲线形状及位置的影响。在此基础上提出：锰－硼钢等温转变 曲线河湾形状的形成原因是由于河湾所在温度范围内锰、硼之间较强的交互作用所引起 的锰、硼偏聚的相互促进而产生较强的溶质拖曳作用的结果。

| Abstract: | Based on experimental analysis of isothermal transformation diagrams (T T T curves) of various Mn-B steels, detailed discussions are made on the influence of elements Mn and B and the Mn-B interaction on the shape and position of T T T curves. It is suggested that the bay-like shape of T T T curves in the invesgated steels should be principally contributed to the stronger solute drag like effect due to the mutually enhanced segregation of Mn and B, which is caused by the strong interaction between Mn and B at the intermediate temperature range. |
