贝氏体分上贝氏体和下贝氏体。粒状贝氏体和准贝氏体为贝氏体转变的初级阶段 ;粒状组织不属于贝氏体。各类组织均有自己的C曲线。由C曲线组成中温TTT图 ,能形成几个海湾。贝氏体预相变期发生溶质原子偏聚 ,贫溶质区即形核位置。贝氏体在溶质原子扩散影响下相变基元沿缺陷面方向切变而增宽 (厚 ) ,板条端部区相变基元平行叠加而伸长。贝氏体在晶体学上有切变性质 ,在热力学上有切变可能。
Bainite bainite and lower bainite. Granular bainite and quasi-bainite bainite transformation of the initial stage; granular tissue does not belong to bainite. All kinds of organizations have their own C curve. By the C curve temperature TTT chart, can form a few bays. Bainite pre-phase transition occurred solute atomic segregation, lean solute region that nuclear position. Under the influence of solute atom diffusion, the phase change element broadens (thick) along the defect plane, and the phase change primitives in the end region of the slab strip overlap and elongate. Bainite crystallographically shearing properties, in the thermodynamic shear may.
