Abstract

Recrystallization kinetics of 75% cold rolled Al- 6Mg alloy with ternary scandium is analyzed from the micro-hardness variation. Isothermally annealed aluminum alloy samples were also studied using JMAK type analysis to see if there exists any correlation between the methods. Recrystallization fraction between two methods, the scandium added alloys show the higher variation due to precipitation hardening and higher recrystallization behavior. From the microstructure it is also observed that the base Al-Mg alloy attained almost fully re-crystallized state after annealing at 400 °C for 60 minutes. 
