    摘要: The invention is a procedure for dynamic deep etching and particle extraction for aluminium alloys, applicable for quality control of products made of aluminium alloys, and for investigation of aluminium alloys using scanning and transmission electron microscopy, as well as X-ray diffraction. The mode and sequence of individual stages of the procedure enables uniform dissolution of aluminium matrix throughout the entire volume of a specimen by using a solution composed of iodine, tartaric acid and methanol, in which the components have concentrations determined according to specimen dimensions. It is important in this regard that the solution penetrates into the interior of the specimen at specific sites only and that the surface oxide layer remains compact. An ultrasonic device is applied in the procedure, effecting the movement and penetration of the electrolyte into the interior of the specimen, and thus enhancing the dissolution process.
