摘要
应用背散电子衍射技术,通过分析Al-Mg-Si-Cu合金板材轧间不同退火处理后的织构变化,研究了轧间退火对该合金板材织构的影响。结果表明:轧制时的中间退火制度不同,各试样中的织构类型及强度有较大变化。没有进行轧间退火处理的试样中存在较强的偏转G取向、Q取向及残留轧制铜C取向。经350℃×1 h轧间退火处理的试样中存在很强的G取向、Q取向及R/S取向。经510℃×1 h轧间退火处理的试样中存在较弱的偏转G取向、R/S取向。每个试样中都含有{111}面织构,经过轧间退火处理的试样中该织构含量较多。
The effects of annealing between rolling on textures of Al-Mg-Si-Cu based alloy sheets were investigated by electron back scattering diffraction（EBSD）.The results show that the type and the intensity of textures changes significantly with different annealing treatment between rolling in samples： some texture components appeare such as relatively strong deflected G orientation,Q orientation and C orientation in the sample without annealing treatment between rolling.Some texture components occur such as very strong G orientation,Q orientation and R/S orientation in the sample annealed at 350 ℃ for 1 h between rolling.Some texture components occur such as weak deflected G orientation and R/S orientation in the sample annealed at 510 ℃ for 1 h between rolling.Every sample contains {111} face texture whose content is more in the samples with annealing between rolling than that in the sample without annealing.
