The Effect of Al Content on the Microstructure and Mechanical Properties of Mg-6Gd-3Y Alloy

Key Points

• Mechanical properties increased with higher aluminum content, leading to enhanced strength and ductility.
• Gaining up to 30% improvement in tensile strength at optimal aluminum concentrations, while maintaining ductility.
• Analysis of alloy composition and microstructure via scanning electron microscopy reveals critical intermetallic phases.
• Indications suggest that optimizing aluminum levels could lead to advanced lightweight materials for automotive applications.
