| Fig.6 Verical section of wCo∶wTi = 1∶1 for the phase diagram of the Gd-Co-Ti system (a) and schematic of the solidification process of the Gd-2%Co-2%Ti alloy under equilibrium conditions (b) (wCo and wTi—mass fractions of solutes Co and Ti, respectively. L1 + L2 represents liquid-liquid phase transformation region. T—temperature. T1, T2, T3, and T4 represent the equilibrium binodal line temperature, onset temperature of liquid-liquid-solid phase transformation, and temperatures of the invariant reactions 1 and 2, respectively) |
