Abstract EN
The hot deformation behavior of an AZ81 magnesium alloy was investigated by hot compressive testing on a Gleeble-1500 thermal mechanical simulator in the temperature range from 200 to 400°C and in the strain rate range of 0.001–5 s − 1 .
The relationships among flow stress, strain rate, and deformation temperature were analyzed, and the deformation activation energy and stress exponent were calculated.
The microstructure evolution of the AZ81 magnesium alloy under high deformation was examined.
The results indicated that the maximum value of the flow stress increased with the decrease of deformation temperature and the increase of strain rate.
When the deformation temperature is constant, the flow stress of the AZ81 magnesium alloy increases with the increase of strain rate, which can be demonstrated by a Zener-Hollomon parameter in a hyperbolic-sine-type equation with a hot compression deformation activation energy of 176.01 KJ/mol and basic hot deformation material factors A, n, and a in the analytical expression of the AZ81 magnesium alloy flow stress of 3.21227 × 10 14 s − 1 , 7.85, and 0.00866 MPa, respectively.
