Abstract
A method for forming a solid solution alloy crystal includes forming a solid solution alloy crystal having at least the same diameter as a seed crystal. The seed crystal is exposed to a liquid containing a desired concentration of an alloying element to dissolve a portion of the seed crystal. The solid solution alloy crystal is then formed from the liquid. The method allows a large diameter solid solution alloy crystal to be grown in a reduced time or a larger diameter solid solution alloy crystal to be grown in a known fixed total process time.
