- •
After aging treatment, the eutectic phase of Mg-Gd-Y-Nd-Zr alloy can dissolve into α-Mg matrix completely.
- •
The massive particle phase distributes in grain boundary and its number increased significantly.
- •
The tensile strength and yield strength are improved significantly from as-cast to aging state.
- •
The Gd after dissolved into α-Mg matrix can lead to serious lattice distortion and improve the antiphase domain boundary.
