The recycling of Al alloys has important economic and environmental incentives. The research focuses on removing impurity elements from secondary aluminum melts through crystallization-based separation methods, aiming to upgrade recycled aluminum into high-value materials. This topic is highly relevant to sustainable metallurgy, circular economy, and future lightweight materials.

The thesis includes alloy preparation, thermodynamic calculations, controlled solidification and crystallization, chemical/microstructural characterization, and investigation of impurity separation mechanisms.
