摘要： A liquid metal cooled directional solidification process provides improved solidification characteristics at the solidification front. In the process, a mold (16) is filled with molten metal; and a solidification interface is caused to pass through the molten metal by progressively immersing the mold into a cooling liquid. The cooling liquid is a eutectic or near eutectic metal composition. A directional solidification furnace (10) includes a heating furnace (14), a liquid cooling bath (20) and a mold positioner (18). The heating furnace (14) has an open bottom end through which a heated mold containing molten metal is lowered from the furnace. The liquid cooling bath (20) comprises a molten eutectic or near eutectic metal composition positioned beneath the open end of the furnace. The mold positioner (18) gradually lowers the heated mold (16) from the furnace (14), through the open end and immerses the mold into the liquid cooling bath (20).
