Zusammenfassung:The softening behavior as a function of recrystallization has been characterized for non-heat-treatable aluminium alloys. All the hot and cold rolled alloys were annealed isothermally at 300°C for different time periods from 15 seconds to 60 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminium alloys were also studied using JMAK type analysis to see if there exists any correlation between the methods. Recrystallization fraction behavior between two methods the Mg added 5xxx alloy shows the minimum variation due to ineffectiveness of its intermetallic phase to retard recrystallization. On the other hand 1xxx, 3xxx and 4xxx series alloys show more variation due to the formation of Fe, Si and Mn rich intermetallic which inhibit recrystallization and grain growth. From the microstructure it is also observed that 5xxx series alloys are almost fully recrystallized after annealing at 300°C for 60 minutes.
