摘要：
The Al ― Mg ― Si phase diagram was studied and the formation conditions for a regular two-phase eutectic structure (α-Al + Mg2Si) were established. Concentration limits were found for optimum alloy compositions with maximum melting point (∼595°C) and a narrow (or zero) melting (crystallization) range (less than 5°C). The structures of these alloys are formed by Mg2Si monocrystal fibers and lamellae with a high degree of ordering, located in the aluminum matrix.
