Abstract

Macrosegregation in metal alloy castings and other alloys having similar solidification behavior is reduced by slowly rotating a mold or the like containing the liquid alloy about an axis at an acute angle to the vertical from the time the liquid alloy is poured into the mold until substantially all of the alloy has solidified. The mold is rotated at a speed below that which produces a centrifuging effect or causes stirring or agitation of the interdendritic liquid.
