Abstract：

Forging-out of the as-cast AZ80 magnesium alloy was researched and the main mechanical properties target were tested at room temperature and high temperature. The results show that the temperature, deforming rate, each pass pressing download and feeding length of each time have a great influence on the deformation of the magnesium alloy. The reasonably technology parameter control can obtain the ideal forging result. At room temperature ,the strength increases with the increasing of forging ratio. Under the tensile temperatures of 250,300,350 and 370 ℃, the according strengths would be shown as 103.5,54.7,26.6 and 18.4 MPa. The plasticity raised during the temperature of 250-300 ℃, but went down during 350-370 ℃.
