“…The low melting temperature of Mg-Zn intermetallic phases (341 C) can cause significant evaporation of Mg and selective oxidation at high temperatures [94]. In addition, Zn tends to sublime [80], which leads to the formation of pores within both the matrix and the oxide scale, accelerating cracking of the oxide scale [42].…”

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.

“…Furthermore, the presence of fine grains could improve the alloy strength. If all the alloys only exhibit grain refinement strengthening, and the value k is 300 MPa mm 1/2 [26], the calculated increment of YS for the AC2, AC4 and AC6 alloys compared to the AC1 alloy would be 9 MPa, 81 MPa and 50 MPa, respectively. However, the experimental values are 2 MPa, 93 MPa and 82 MPa, respectively.…”
