采用背散射电子衍射(EBSD)分析方法,研究了退火温度和时间对新型超低碳烘烤硬化钢再结晶织构的影响。分析了取向差、取向分布函数和fiber线等试验数据。研究结果表明:在再结晶完成的条件下,延长退火加热时间和提高退火温度,会降低BH钢的{111}面织构的取向密度,并会增加{100}面织构的取向密度。

The effects of annealing temperature and time on the recrystallization texture of new ultra low carbon bake hardened steel were studied by backscattered electron diffraction (EBSD). The experimental data of orientation difference, orientation distribution function and fiber line were analyzed. The results show that under the condition of recrystallization, prolonging annealing time and increasing annealing temperature will decrease the orientation density of {111} plane texture and increase the orientation density of {100} plane texture.
