Microstructure and electronic characteristics of the 6H-type ABACAB LPSO structure in Mg97Zn1Y2 alloy

Crystal structure of the mirror symmetry 10H-type long-period stacking order phase in Mg–Y–Zn alloy

“…In recent years, Mg-Y-Zn alloys have received considerable attention due to their excellent mechanical properties and unique microstructures [11][12][13][14][15][16][17][18][19][20]. In particular, various novel lamellar structure of long-period stacking order (LPSO) phases have been observed, including 6H, 10H, 14H, 18R and 24R [21][22][23][24][25][26][27][28][29][30][31].…”

Structural, elastic and electronic properties of Mg(Cu1−xZnx)2 alloys calculated by first-principles

“…However, their applications are also restricted because of the limited tensile strength and inferior ductility. Hence, there is an urgent need to improve the mechanical property of magnesium alloys, and much effort has been devoted to developing high-strength magnesium alloys with good ductility [6,7].…”

First-principles investigation of the structural and mechanical properties of β″ phase in Mg–Gd alloy system

“…It is shown that the mechanical properties of Mg alloys could be improved remarkably by the addition of rare earth metal [3]. Therefore, Mg-rare earth alloys have received great interest from both the experiment and theory [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…So many investigations have been done on the Mg-Gd base alloys [6][7][8][9][10][13][14][15]. For Mg-Gd binary alloy, the precipitation sequence of the ␣ -Mg supersaturated solid solution with increasing temperature was as follows: Mg (S.S.S.S) → ␤ (D0 19 ) → ␤ (cbco) → ␤ (Mg 5 Gd f.c.c.) [20].…”

“…On the other hand, another precipitation sequence for Mg-Gd-Y-Zr alloy was also proposed as: S.S.S.S. → ␤ (D0 19 ) → ␤ (cbco) → ␤ 1 (fcc) → ␤ (fcc) [21]. It was found that the formation of fine ␤ phase particles led to a maximum in the hardness of Mg-10Gd (wt%) alloy [22], and the ␤ phase was also mainly responsible for the small increase in the age hardness in initial stage of Mg-10Gd-3Y-0.4Zr (wt.%) alloy [21].…”
