Experimental determination of the phase equilibria of the Mg–Nd–Zn system at 320°C

•The 320°C isothermal section of the Mg–Nd–Zn system was well established.•Eight ternary phases (τ1–τ7 and T-NdMg12) were found at 320°C.•T-NdMg12 is the Nd-stabilized NdMg12 phase.•T-NdMg12 and τ5–τ7 can be regarded as the newly found ternary phases.
