Abstract
In the present study the kinetics of recrystallization phenomenon of hot-rolled Mg-1.33La (wt.%) alloy was investigated using differential scanning calorimetry (DSC) analysis. The alloy was hot-rolled at 693 K to 20 and 50 % of thickness reduction. The DSC experiments results showed that the peak of recrystallization process ranged from 441.9 ± 2.0–497.8 ± 4.0 K and increased with increasing heating rate. The activation energy evaluated through the non-isothermal DSC treatment ranged from 93.3 ± 2.1–116.6 ± 2.6 kJ mol−1 and correlates well with the increase of stored energy during the deformation processing. The Avrami exponent of recrystallization was found close to 0.6 which indicates that the recrystallization preferentially occurred along grain boundaries and within deformation features such as twins.
