- •
Four zones were identified in a melt-back seed of seeding-grain selection technique.
- •
Seeding-grain selection technique can prevent stray grain from growing into casting body by geometry blocking of spiral passage.
- •
The final orientation did not change a lot after high-order branching in spiral passage.
