Preparation of Al-Si-Cu alloy metallography sample and display organize method, it includes the following steps: a. rough grinding: using size reduction water sandpapers in turn, the samples are accomplished at least two times water polished, and after each sandpaper changing rotate 90 degree, until eliminating the scratch of the previous process, and before sandpaper changing, the samples are cleaned with water; b. electrolytic polishing: using the electrolytic polishing machine, polish at least two times, and after each time, rinse and cool with water; c. flannel polishing: samples polish on the single direction with the polishing pasted silk cloth; d. chemical etching: the etchant is dropped on the sample surface, eroded using wipe-mop method. Compared with the existing technologies, the advantages of the invention is to take electrolytic polishing and flannel polishing at the same time, combining chemical corrosion, optimized selecting the etchant of HF:HCl:H2O=2:3:18, to successful prepare metallographic examination samples. It is a high efficiency for sample preparation, low labor intensity, and it is the technology to obtain a very clear and integrity crystal boundary.
