Abstract The microstructures of Mg–6Zn–1Y (at%) alloys cooling in the 20° C water and 20° C air respectively from semisolid state at 540° C were investigated in this work. An (α-Mg+ I-phase) nano-eutectic was discovered in the water-cooled samples. The details of the nano-eutectic were investigated under TEM. Compared with the face-centered icosahedral I-phase solidified at slow cooling rate, the icosahedral type of I-phase solidified at fast cooling rate is primitive. The orientation relationship of the two phase in the nano-eutectic was also studied, namely {01 1 ̅ 1 ̅} Mg∥{τ 10} I− phase and {10 1 ̅ 0} Mg∥ 2 f I− phase. The two phases with different lattice structure matched as semi-coherent, which indicated that the interface was in a low energy state.
