| Abstract: | High temperature deformation behavior of GWZ1031 K magnesium alloy was investigated by high temperature tensile test at 250-400℃ and the deformation rate of 0.2 mm/min.Scanning electron microscope(SEM)and X-ray energy spectroscopy(EDS)were used to observe the microstructure and tensile fracture.The results show that the peak value appears in all the high temperature tensile stressstrain curves at different temperatures,and the peak stress decreases with the increase of deformation temperature,meanwhile the plasticity increases sharply,particularly superplasticity occurs at 400℃.Combining the analyse of microstructure and fracture morphology,it can be concluded that the GWZ1031 K magnesium alloy has good heat resistance in the temperature range from 250℃ to 350℃. |
