1.
The observations by OM and TEM reveal that when undeformed austenite continuously cooled at 10 to 30℃/s,bainitic ferrite nucleated mainly at austenite grain boundaries,grown up like parallel lath into the bulk from the grain boundaries of austenite,and original austenite grain boundaries could be seen.
经OM和TEM观察表明,当未变形奥氏体以10~30℃/s连续冷却时,贝氏体铁素体优先在奥氏体晶界处形核,然后呈板条状从奥氏体晶界向晶内长大,并且可以从最终的组织看到原奥氏体晶界。
2.
The method of system science was used to study the nucleation and growth mechanism, substructure of bainitic ferrite, phase transformation dynamics.
运用试验与综合分析的方法,通过对贝氏体相变的形核、长大,贝氏体铁素体的亚结构、相变动力学的综合研究和分析,认为贝氏体相变机制具有过渡性,既非切变机制,也非台阶扩散机制,并提出了切变-扩散整合机制。
3.
The fine structural units and their size were different structural levels in the bainitic ferrite were determined by retained austenitic films.
透射电镜分析表明,贝氏体铁素体内有不同形貌、尺度的残余奥氏体膜存在,它们把贝氏体铁素体分割或包围为不同层次结构单元,以残余奥氏体膜为分界面确定了贝氏体铁素体不同层次的精细结构单元及尺度。
