In this work, a comprehensive analysis was performed to assess the impact of chemical and physical modifying in fluences on the structural formation of cast metal matrix composites with in-situ formed reinforcing phases, using the pseudo-binary Al – Mg₂Si system as a case study. Relevant problematic issues were identified, and prospective approaches to controlling the structural-morphological parameters of aluminum matrix composites during melting and crystallization were determined. Recent advancements in investigating the influence of thermal-rate and electromagnetic pulsed processing of melts on the structure of in-situ aluminum matrix composites were summarized. An evaluation of the influence of various modifying elements on the structure of pseudo-binary aluminum alloys and composites was provided. The feasibility and effectiveness of employing alkali and alkali-earth metals for the modification of Al – Mg₂Si aluminum matrix composites were confirmed, replacing expensive rare-earth metals. Additionally, it was demonstrated that lithium yields the most significant modifying effect, considering a complex assessment of its impact on the structure.
