Aluminium alloys contain many phases that can form during solidification, heat treatment, and thermomechanical processing. Their type, size and morphology have a significant influence on different properties of the alloys, thus determination of all their geometrical features is very important. Knowing the 3D particle shapes is essential not only for choosing the best processing routes for common alloys but also for designing new alloys.
A patented procedure of Dynamic deep etching and extraction of particles was used for analysing particles in aluminium quasicrystalline alloys and several high-strength aluminium alloys.
The mode and sequence of individual stages of the procedure enabled the uniform dissolution of aluminium matrix throughout the entire volume of a specimen. An ultrasonic treatment facilitated the penetration of the electrolyte into the specimen. The results were deep-etch and powder samples that enabled thorough characterization of particles using different techniques.
