Oxidation resistance of B2 rare earth–magnesium intermetallic compounds

First-principles study of B2-like intermetallics LaMg and YMg

“…Among the magnesium alloys, LaMg and YMg compounds have been attracting much attention for several decades owing to their high oxidation resistance and high temperature strength [4,5].…”

“…Stumphy et al [4] investigated the oxidation behavior of YMg by thermal gravimetric analysis technique. On the theoretical side, the electronic band structures calculated for LaMg and YMg were reported by Khadeer Pasha et al [14], that for LaMg by Wang et al [16], and that for YMg by Divi s et al [19,20].…”

Study on the intermetallic phases in the Mg–Ce system

“…The mechanical (elastic moduli) and thermodynamic properties of the C-15 Mg 2 Ce Laves phase was recently calculated from first principles by Ouyang et al [20], it was concluded that the Mg 2 Ce would be more ductile than the MgCe and the Mg 3 Ce phases. Oxidation studies on the CeMg intermetallic [21] showed that negligible oxidation is observed at room temperature.…”

Study on the microstructural evolution of different component alloys consisting of B2-NiSc intermetallics

“…Further study showed when plastic deformation of RM single crystal begins, that only the {100} <010> and {110} <010> two independent slip systems were found, which was contrary to the Von-Mises criterion [2][3][4]. Mulay et al discovered that the second phase in RM (AgY, CuY, AgEr, CuDy, MgY and MgCe) intermetallics had a great influence on the ductility of B2 intermetallics [6][7]. Therefore, revealing the ductility of B2 structure is not only a hot area of research right now, but it also has important theoretical significance.…”
