| 摘 要： | 对变形量为40%,厚度为1.8mm的冷轧4J6合金薄带施以不同温度相同保温时间的退火处理,采用金相组织观察,电子背散射衍射(EBSD)实验手段,研究了不同温度退火条件下,冷轧4J6合金薄带的显微组织和主要织构的演变规律以及晶界的取向差分布特征。结果表明,随着退火温度的增加,小角晶界的取向差逐渐减小,晶界的取向差主要分布在55°～60°之间;高斯织构及黄铜织构所占比例逐渐减小,<110>//RD织构逐渐增加。

| Abstract: | The cold-rolled(reduction of 40%)4J6 alloy strip of 1.8 mm in thickness was annealed at different temperatures.By means of optical microscopy and EBSD analysis,the microstructure and main texture evolution and grainboundary misorientation distribution characters in 4J6 alloy strip under the different annealing parameters were investigated.The results showed that the amount of low-angle grain boundaries decreased with the increase of the annealing temperature.Under the same parameter,the amount of Goss texture and Brass texture decreased with the increase of the <110>//RD texture. |

| Keywords: | electron back-scattered diffraction (EBSD) 4J6 alloy sheet texture grainboundary misorinetation distribution |
