摘 要: 采用织构定量检测、EBSD微取向分析、晶粒尺寸分析等手段研究了退火加热过程对高压电解电容器阳极铝箔立方织构的影响。结果表明:铝箔在最终退火加热中分别经历了初次再结晶和晶粒长大两个主要过程,两过程互有重叠,其中在300℃适当完成初次再结晶并在500℃促使立方取向晶粒长大有利于提高最终的立方织构量;在500℃长时间加热有可能诱发晶粒异常长大,并降低立方织构量。

Abstract:The influence of annealing process on the cube texture formation in aluminum foil of high voltage anode electrolytic capacitor was investigated using the quantitative texture analysis,EBSD micro-orientation analysis,as well as grain size measurement. It is shown that the two main processes of primary recrystallization and grain growth are carried out during the final annealing. The two processes are overlapped each other in certain extent,in which strongercube texture can be formed if the primary recrystallization is completed properly at 300 ℃ and the cube grain grow further at 500℃. The annealing at 500℃ for very long time will induce an abnormal grain growth and reduce the cube texture component.
