- •
Mg–3Nd–0.2Zn (NZ30) and Mg–3Nd–0.2Zn–0.4Zr (NZ30K) alloy semisolid slurries were prepared by electromagnetic stirring.
- •
Increase of voltage or decrease of frequency led to the increase of undercooling and melt temperature.
- •
The optimal parameters for Mg–3Nd–0.2Zn and Mg–3Nd–0.2Zn–0.4Zr alloy slurries were obtained.
- •
Three types of primary α-Mg particles were obtained in NZ30 alloy semisolid slurry: rosette, dendrite, and spheroid.
