A supersaturated solid solution containing 1.6 W/o chromium was formed by cooling AI-2W/o Cr alloy at rates greater than 1250°C/s from the liquid state. On annealing, the alloy preferred to transform to the stable CrAI7 phase without revealing the predominance of vacancy solute clusters as evidenced in Al-Mn system. The activation energy for the growth of CrAl7 was found to be between 0.40 to 0.50 ev and the degree of supersaturation was found to vary exponentially with the, cooling rate.
