Abstract of the Disclosure Disclosed is a method of epitaxially casting single crystal metal articles in molds, which com- prises causing the solidification interface velocity vector to rotate through at least 90 degrees, pre- ferably 180-540 degrees, about the axis of overall directional solidification growth. In addition, a mold section has a small passageway configured to prevent line of sight communication between the por- tion where the seed is contained and the article portion of the mold. Preferably, the passageway is shaped like a helix of 0.8-1.5 turns. A second seed can be formed in the mold of an article made from a first seed, and used to make a second casting. The invention reduces the normal increase in crystallo- graphic variability which would otherwise be associ- ated with such practice.
