1.
It was found that an upper bainitic transformation,γ→α-Fe+γ′-Fe_4N,occurred preferentially at either the grain boundaries or the dislocation lines in the interior of austenite grains,producing a microstructure which,although morphologically looking markedly different,consisted of bainitic packets composed of parallel bainitic ferrite(α-Fe)laths withγ′-Fe_4N lath.

3.
, segregate at grain boundaries or other defects, and even the carbide may precipitate, resulting in the increase of the driving force for nucleation, in turn, marked raise of the nucleation rate and acceleration of incubation for bainitic transformation.
外加应力使贝氏体相变形核率增大,等温孕育期缩短,即使所加应力远低于母相的屈服强度,由于钢中γ→α+γ的形核驱动力较大(约为kJ/mol数量级),贝氏体相变的膨胀应变能很小,过小的外加应力对形核率的影响甚微,考虑在外加应力的影响下,会使界面能量有所下降,也可能发生碳原子的再分布,偏聚在晶界或其它缺陷,甚至碳化物析出都会显著地增大形核率和缩短孕育期,有待进一步实验给予证明,无应力下,贝氏体相变动力学可以用Avrami的等温相变方程来表述;应力下则符合应力下铁素体及珠光体相变的动力学模型(经修改的Avrami方程),形变奥氏体促发贝氏体相变,但随后会发生奥氏体的力学稳定化,其机制可能和马氏体相变时的奥氏体力学稳定化不完全相同,仅形变形成的位错阻碍贝氏体以一定位向长大,使相变动力学迟缓,贝氏体相变时奥氏体力学稳定化的模型有待建立。

补充资料:奥氏体-贝氏体球铁
分子式:
CAS号:

性质:又叫奥-贝球铁。基体组织为奥氏体加贝氏体组织的球墨铸铁。这类球铁硅含量一般在1.4%~3.8%。含锰量小于0.5%,与普通球铁比较硅偏高、锰偏低。通过调节化学成分与热处理获得理想的奥-贝球铁的基体组织为针状贝氏体或无碳贝氏体一富碳奥氏体。这类球铁具有优良的综合机械性能、强度高、耐磨性好、韧性好、特别是有高的缺口韧性,可代替钢,用于制作重要受力结构件,如曲轴、齿轮、凸轮轴等。
