Abstract A new technology of grain refinement of metals, self grain refinement, obtained by the utilization of the nucleation potential inherent in commercially pure Al, Cu andSb has been described. The effects of the cooling rate, adding amount and holding time inmolten metal for the rapidly solidified sheet of these metals on self grain refinement have beenexamined. The effectiveness of the self grain refinement of aluminium is equal to that of amaster Al-Ti-B added in the aluminium. Cu and Sb also have the effectiveness of the selfgrain refinement. The mechanism of the self grain refinement of metals has been studied onthe heredity theory of metals.
