1) Heat activation transition
热激活跃迁
1.
The nucleation is at boundary in bainite phase transformation which is the diffusive less γ→α transformation at carbon-poor area but shear process,and nucleation and growth by heat activation transition of interface substitution atoms.
指出了过渡性是贝氏体相变的主要特征;提出了贝氏体的新定义和贝氏体相变的新机制;贝氏体相变在晶界形核,晶核是单相贝氏体铁素体(BF),不是BF共析分解;在贫碳区形核,是贫碳的γ→α的无扩散相变,不是切变过程,而是以界面替换原子非协同热激活跃迁方式形核长大;钢中贝氏体碳化物(Bc)在γ/α相界面上形核,向BF中长大,最终被铁素体包围,也是以界面原子热激活跃迁方式进行的。
