Abstract
A method includes providing a mold including a molten casting material, moving the mold in a first direction, and guiding a solidification interface across the mold in a second direction in response to the moving the mold. The second direction is deviated from the first direction, and the solidification interface includes a transition to a negative heat transfer region. The mold moves in the first direction at a constant speed, and the mold includes heat transfer features such that a solidification time of the molten casting material at the conditions of the solidification interface is approximately constant as a function of the second direction.
Claims21
A method, comprising:
- providing a mold including a molten casting material;
- moving the mold in a first direction;
- and
- guiding a solidification interface across the mold in a second direction in response to the moving the mold, wherein the second direction is deviated from the first direction, and wherein the solidification interface comprises a transition to a negative heat transfer region.
A system, comprising:
- a furnace including a solidification interface;
- a mold including a molten casting material;
- a guide that moves the mold in a first direction;
- and
- wherein the solidification interface traverses across the mold in a second direction in response to the mold moving in the first direction, wherein the second direction is deviated from the first direction, and wherein the solidification interface comprises a heat source region on a first side and a heat sink region on a second side.
