System, method, and apparatus for directional divergence between part motion and crystallization

摘要

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.

1. A method, comprising:
sequentially providing a plurality of molds including molten casting material; sequentially moving the plurality of molds in a first direction; and sequentially guiding a solidification interface across the molds in a second direction in response to the moving the molds effective to advance a solidification front of the casting material along a respective mold axis of a respective mold extending in the second direction, wherein the second direction is deviated from the first direction, wherein the solidification interface comprises a transition to a negative heat transfer region, and wherein the solidification interface is deviated from the first direction at a non-perpendicular angle and, at the location at which the solidification interface is guided across a respective mold, the solidification interface is deviated from the respective mold axis of the respective mold extending in the second direction at a non-perpendicular angle.
