The preparation of Al-Si cast alloys specimens for TEM observa tionsMieczyslaw Kaczorowski

An original method for preparing thin foils from Al-Si cast alloys is described. This simple method consists of one - jet electropolishing accompanied with ultrasonic "cleaning". The aim of this ultrasonic bath is to remove eutectic Si precipitates forming a specific "skeleton" in the specimen. This framework hinders the process of polishing and makes TEM observations more difficult, especially when high angle tilting is used.
