针对1235双零铝箔生产中出现的铝箔断带的现象,采用扫描电子显微镜、X射线衍射仪、能谱仪和电子探针显微分析仪对断带断口进行成分和物相分析,得出Mg2Si相、Al3Mg2相、少量的FeAl3相和一些杂质AlFeSi相是产生断带的主要原因。利用CMT8502微控电子万能试验机对成品箔材进行力学拉伸实验,结果发现,除退火后的成品铝箔外,其他道次样品的纵向抗拉强度均略低于横向抗拉强度,可知轧制过程中织构相比于加工硬化对铝箔的力学性能影响更大,铝箔成品力学性能达到国标GB/T3198-2010要求的最高标准。
Aiming at the phenomenon of aluminum foil breakage occurring in the production of 1235 double zero aluminum foil, the composition and phase analysis of the fracture of the rupture band were analyzed by scanning electron microscope, X-ray diffraction, energy dispersive spectrometer and electron probe microanalysis, Phase, Al3Mg2 phase, a small amount of FeAl3 phase and some impurities AlFeSi phase is the main reason for the fault. CMT8502 micro-electronic universal testing machine mechanical tensile test of the finished foil, the results showed that, in addition to the finished aluminum foil after annealing, the other longitudinal tensile strength samples were slightly lower than the transverse tensile strength, we can see that rolling The mechanical properties of the aluminum foil have a greater impact on the mechanical properties of the aluminum foil than the work-hardening during the process. The mechanical properties of the aluminum foil finished products meet the highest standards required by the national standard GB / T3198-2010.
