چکیده انگلیسی
Isothermal compression tests were conducted to predict the hot deformational flow stress behaviour of 2024Al-T3 alloy with respect to a wide range of strain rates (0.001-100 sâ1), strains (0.1-0.5) and temperatures (573-773 K). The prediction capabilities of various constitutive models for 2024Al alloys and a recently developed constitutive model were evaluated using statistical parameters such as the average absolute relative error (AARE) and the correlation coefficient (R). Models recorded the lowest AARE (4.6%) and the highest correlation coefficient (R=0.99) were developed compared with the other models. Hence, this model can track the deformational behaviour of 2027Al-T3 alloy more accurately compared with other models throughout the entire processing domain investigated.
