摘要
利用背散射电子衍射(EBSD)技术,研究了不同连续退火温度下Ti-IF钢微观取向的演变规律,并对不同退火温度下退火板的力学性能进行研究。研究发现当退火温度较低时(780℃)织构分布相对随机,随退火温度升高,ND∥<111>织构比例增加,在860℃退火时得到的r值最高,同时ND∥<111>织构比例最高,但当退火温度继续升高到900℃时,所有取向的晶粒均得到发展,使ND∥<111>织构比例和退火板的r值降低。
Micro-orientations evolution of cold-rolled Ti-IF steel annealed at different temperature was investigated by means of electron back scatter diffraction（EBSD） technique,and the mechanical properties of annealed sheets were studied.The results show that： textures are random distributed at low-temperature（780℃）,with the temperature increasing,ND∥111 texture ratio increases,and the maximum r value and ND∥111 texture ratio at 860℃ are gotten,while the annealing temperature continues to rise to 900℃,all textures are developed,causing the reduce of ND∥111 texture ratio and r value
