【摘要】 运用电子背散射花样技术(EBSP)对本钢深冲板St15再结晶退火过程中的织构演变规律进行了研究.当加热速率为30℃/h时,深冲板St15再结晶开始温度在560℃左右,再结晶完成时间约为2h,最强织构组分为{100}<110>.随着温度的升高,深冲板St15的γ纤维织构,尤其是{111)<112>织构有所增强.当保温温度为700℃,随保温时间延长,深冲板St15的{111}<110>织构明显增强,4h后{111}<112>织构开始逐渐增强,到13h时,获得理想的退火织构.更多还原

【Abstract】 Electrical back scatter pattern (EBSP) was used to investigate the texture evolution rule of deep-drawing sheet St15 during recrystallization annealing. When the heating rate is 30℃/h, the recrystallization temperature of deep-drawing sheet St15 is about 560℃, the recrystallization finishing time is nearly 2 h, and the strongest component of the recrystallization texture is {100}<110>. γ fibre texture in St15, especially {111}<112>, strengthens with incresing the annealing temperature. When the holding temperature is 700℃, {111}<110> texture in St15 strengthens with increasing the annealing time, and after holding for 4h{111}<112> texture gradually. When the holding time reaches 13 h, a satisfied annealing texture is achieved.更多还原
