The mechanical properties of 5083-H111 and 5754-O Al-Mg alloys at various testing temperatures (between room temperature (RT) and 300 degrees C) and strain rates (0.0016-0.16 s(-1)) were determined. A new mathematical model which is based on temperature and strain rate is developed and named as softening model. The model is used to simulate the recorded strain softening behavior of the 5083-H111 and 5754-O Al-Mg alloys at warm temperatures and modeling capabilities of softening model are shown.
