“…As mentioned in the section of Introduction, the formation of the ternary phases depends on the Zn/Y ratio. 2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Summarizing the existing investigations, the following rules can be concluded: Zn/Y < 0.6, only one ternary phase of Z can form; 0.6 < Zn/Y < 0.85, two phases of Z and W will form; 0.85 < Zn/Y < 2.05, only W phase can form. For the present work, the Zn/RE ratios of the alloys with 0%, 0.3%, 0.5%, 1%, 2% and 3% Nd are 2, 1.54, 1.33, 1, 0.67 and 0.5 respectively.…”
