| 发明名称 | Metal casting apparatus, cast work piece and method therefor | ||
| 摘要 | A metal casting apparatus includes a feeder for providing a molten metallic material. A mold includes a sprue and a component cavity. The sprue is arranged to receive the molten metallic material from the feeder and the component cavity is arranged to receive the molten metallic material from the sprue. A starter is arranged adjacent the component cavity and is operable to induce a first grain orientation upon solidification of the molten metallic material. The sprue includes an aborter that is arranged to induce a second grain orientation upon solidification of the molten metallic material. | ||
