Abstract


RECRYSTALLIZATION KINETICS OF COLD ROLLED AA3105 AND AA5005 SHEETS BY DSC ANALYSIS

In this study, the non-isothermal recrystallization kinetics of cold rolled AA3105 and AA5005 aluminum alloy sheets obtained from ASAŞ Aluminum located in Akyazı-Sakarya was studied by using differential scanning calorimetry (DSC). The non – isothermal kinetics was performed by using Kissenger, Boswell, Ozawa and Starink methods known as model – free methods. The recrystallization temperatures on DSC graphics at different heating rates (ß) were deduced and the activation energies were calculated from the slopes from Y – 1/T diagrams. Y is ln(ß/T2) for Kissenger, ln(ß/T) for Boswell, ln(ß) for Ozawa and ln(ß/T1.92) for Starink. The results showed that the activation energies of recrystallization are in the range of 194 – 206 kJ/mol for cold rolled AA5005 sheet and in the range of 235 – 257 kJ/mol for cold rolled AA3105 sheet, according to four non-isothermal kinetics model.
