Figure 2
Stability regions of (a) DQCs and (b), (c) IQCs. RE denotes the rare-earth metals Y, Dy, Ho, Er, Tm, Lu in the case of d-Zn–Mg–RE; Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu in the case of i-Cd–Mg–RE; La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Yb in the case of i-Zn–Mg–RE. Note that only the A-rich parts (50 ≤ A ≤ 100 at.%) of the concentration diagrams are shown in (a) and (c) (the figures are based on Grushko & Velikanova, 2004). |
