Directional solidification could improve hot rolling formability of magnesiumingot effectively. The total deformation could reach 94% without cracking when hot rolling was held at 673k.
The preparation process includes smelting and refining of magnesium alloys and the preparation of semisolid paste or semisolid billet or casting ingot of magnesium alloys.
