Notes:
AA6111 sheet alloy has been used in automotive panel applications in North Americaand Europe for several years. This alloy exhibits an excellent combination of strength,formability, ageing response and surface appearance following forming and painting operations.Such a combination of properties is obtained by carefully tailoring the processing route to obtainthe desired microstructure of the alloy. In recent years, the ability to predict the phase stability indifferent alloys has improved significantly, and it is now relatively easy to predict the particlesthat could form in complex multi component alloys during different processing steps. Theaccuracy of the predictions is dependent on whether or not the free energy expressions used in thecalculations are correct. In this study, the AA6111 alloy was subjected to various annealingtreatments that are reflective of different phase fields computed by the Thermo-Calc software.The particles were extracted using the phenol extraction technique and were identified usingenergy dispersive analysis. The interrelation of the particle analyses with the computed phasestability in AA6111 is presented
