We elucidate here the effects of annealing twins on phase transformation products based on electron back-scatter diffraction analysis and corresponding microstructure visualization and quantification methods. Martensite and bainite were obtained by rapid continuous cooling and isothermal processing at different temperatures, respectively, which were designed to study variants formed in austenite with Σ₃ boundary. The isothermal transformation near martensite start (M_s) temperature was most conducive in obtaining the highest content of twin-related V₁/V₂ variant pair. Based on the classical nucleation theory of martensite and bainite, respectively, the role of austenite Σ₃ boundary in martensite and bainite transformation is illustrated.

我们在此基于电子反向散射衍射分析以及相应的微观结构可视化和定量方法，阐明双晶退火对相变产物的影响。马氏体和贝氏体，通过快速连续冷却和等温处理在不同温度下，分别，其被设计为研究形成于奥氏体变体与所获得Σ ₃的边界。邻近马氏体开始（等温转变中号_小号）温度为最有利于在获得双相关的含量最高V ₁ / V ₂变体对。基于马氏体和贝氏体的经典形核理论，奥氏体的作用分别Σ ₃在马氏体和贝氏体相变边界被示出。
