Title: Flow Stress Behavior of 2519 Aluminum Alloy Under Hot Compression Deformation
Abstract: The flow stress behavior of 2519 aluminum alloy during hot deformation conditions was studied by isothermal hot compression on Gleeble 1500.The deformation temperature is range from 300℃ to 500℃ and the strain rate range from 0.05 s -1 to 25 s -1 .The experimental results indicated that the flow stress of 2519 aluminum alloy increases with increasing strain and tends to be constant after a peak value at lower strain rates ( e· ≤25 s -1 ),showing dynamic recover.The flow stress sawtooth fluctuates after a peak value with the increasing strain at higher strain rates ( e· ≥25 s -1 ),showing discontinuous dynamic recrystallization.The deformation activation energy of 2519 aluminum alloy during hot deformation is 167.81 kJ/mol from Arrhenius equation.
