“…It was already known that Mg 24 Y 5 could gradually dissolve into the matrix during the high temperature oxidation process [18], and the addition of Zn element will lead to the formation of Mg 12 YZn (X) phase in Mg-Y-Zn alloys. Nevertheless, the X-phase was relatively a stable compound [27].…”

“…Zhao et al [16] investigated the oxidation behavior of AZ31 by adding La element, and found that the excellent oxidation resistance could be achieved by the addition of~0.7 wt% La. Recent work found that the oxidation resistance of magnesium alloys could be improved significantly by the addition of Y [18,19]. The dissolved Y element in the matrix was beneficial to improve the oxidation resistance of magnesium alloys [19].…”

Highlights The oxidation behaviours of Mg alloys from low to high temperatures are reviewed. Characteristics of MgO during oxidation is discussed. Mechanisms of Mg oxidation is presented. Effect of various alloying elements is analysed. AbstractThis paper reviews (i) the oxidation of Mg alloys at elevated temperatures in air; (ii) the influence of alloying elements on the oxidation of Mg alloys; and (iii) the progress in the development of oxidation-resistant Mg alloys. Low oxidation rates have been shown by Mg alloys containing the alloying elements, Ca, Be and rare earth elements. However, these alloying elements may also decrease mechanical properties, such as ductility.

Mg-0.5Si-xSn (x=0.95, 2.9, 5.02wt.%) alloys were cast and extruded at 593K (320 o C) with an extrusion ratio of 25. The microstructure and mechanical properties of as-cast and extruded test alloys were investigated by OM, SEM, XRD and tensile tests. The experimental results indicate that the microstructure of the Mg-0.5Si-xSn alloys consists of primary α-Mg dendrites and an interdendritic eutectic containing α-Mg, Mg 2 Si and Mg 2 Sn. There is no coarse primary Mg 2 Si phase in the test alloys due to low Si content. With the increase in the Sn content, the Mg 2 Si phase was refined. The shape of Mg 2 Si phase was changed from branch to short bar, and the size of them were reduced. The ultimate tensile strength and yield strength of Mg-0.52Si-2.9Sn alloy at the temperature of 473K (200 o C) reach 133MPa and 112MPa respectively. Refined eutectic Mg 2 Si phase and dispersed Mg 2 Sn phase with good elevated temperature stability are beneficial to improve the elevated temperature performance of the alloys. However, with the excess addition of Sn, large block-like Mg 2 Sn appears around the grain boundary leading to lower mechanical properties.
