| Abstract: | The microstructure of cast Al-Si alloys is special, making it difficult to prepare electron backscatter diffraction (EBSD) samples. In this study, the commonly used methods for preparing EBSD samples of cast Al-Si alloys were reviewed, including electro-polishing, ion milling, and vibration polishing. The performances of different methods in experimental periods, operability, cost, and surface quality of samples were compared and analyzed. Taking ZL114A alloy as the actual operating alloy, samples were prepared by the above methods and analyzed by EBSD. Experimental results show that when observing and analyzing the microstructure of Al-Si alloy(such as grains and eutectic Si), appropriate EBSD preparation methods should be selected according to different analysis requirements, analysis objects, and analysis precision. |
