Magnesium Alloys with Enhanced Ignition Resistance for Aerospace and Automotive Applications

Original language description

Magnesium alloys, known for their excellent strength-to-weight ratio, are emerging as promising materials in the automotive and aerospace industries. In this study, we explored three magnesium alloy systems enriched with rare earth (RE) elements and calcium: Mg-4.5Gd-3.4Y-2.6Ca, Mg-2Y-2Gd-1Ca, and Mg-4Ca-1Y (weight %). These alloys were prepared through casting and then extruded at temperatures of 300°C, 350°C, and 400°C, with extrusion ratios of 11 and 25. This approach allowed us to examine the effects of both composition and processing techniques on the materials. The microstructure primarily consisted of a solid solution of magnesium and the Mg2Ca phase, along with minor amounts of RE-hydrides, RE-oxides, and Mg-RE particles. Notably, extrusion at 400°C resulted in a larger grain size (5.5 μm) compared to lower extrusion temperatures (around 2.5 μm). The obtained results showed the exceptional ignition resistance of these alloys. The ignition temperature ranged from approximately 950°C for Mg-2Y-2Gd-1Ca to over 1100°C for Mg-4.5Gd-3.4Y-2.6Ca and Mg-4Ca-1Y. This high resistance results from the synergistic effects of Y, Gd, and Ca oxides. Compression tests revealed that alloys with higher RE content exhibited superior mechanical properties compared to those with more calcium. However, the latter still achieved remarkable ignition resistance at a lower cost. Future research aims to enhance the mechanical properties of the Mg-4Ca-1Y alloy without compromising its impressive ignition resistance, potentially making it an even more attractive material for high-performance applications.
