Abstract:
A method of directionally solidifying a molten alloy is presented. The molten alloy is disposed in a shell mold that has a thermal conductivity value greater than about 2 W/m-K. During the direction solidification, heat is transferred from the shell mold to a cooling region with a heat extraction rate greater than about 120 W/m2.
