Abstract:

The recrystallization process of Mg-Ce alloy after high-pressure torsion (HPT) was investigated using differential scanning calorimetry (DSC) technique. The DSC results show that the recrystallization peak temperature increases with increasing the heating rate which confirms that recrystallization is thermally activated and kinetically controlled. The recrystallized volume fraction, the rate of recrystallization, the transformation function and the kinetic parameters (activation energy and Avrami exponent) for Mg-Ce alloy were estimated using several analytical approaches.
