Ignition Resistance of Pure Mg, ZM5 and ZM6 Magnesium Alloys

Abstract The use of magnesium alloys in aerospace is relatively restricted by their poor ignition resistance performance. A continuous heating test was conducted to investigate the pure Mg, ZM5, and ZM6 with different alloying elements. It found that elements greatly influenced alloys. With about 2% addition Nd rare earth element, had a higher temperature than Mg. In comparison, which contains mainly 8% Al lower Analysis high-temperature surface oxide film reveals resulted from protective 2 O 3 formed on oxidized surface. Alloying earths can improve
