This is a standard method for the quantitative analysis of the internal crystal structure of aluminum and aluminum alloy foils. It specifies the methods for determining the content of "cube texture" in aluminum foil, which directly affects key properties such as deep drawing formability. The standard recommends multiple detection methods, including electron backscatter diffraction (EBSD) and X-ray diffraction (XRD) pole figure methods, with the electron backscatter diffraction method designated as the arbitration method. The core instruments for implementing this standard are scanning electron microscopes equipped with relevant functions (for the EBSD method) or X-ray diffractometers, which are used to obtain crystal orientation information of the material and calculate the cube texture content through software analysis. This standard provides a unified technical basis for evaluating and controlling the microstructure quality of aluminum foils.
