Research on forging-out and mechanical properties after forging of AZ80 magnesium alloy

DENG Zi-yu1,2,CHEN Xian-gang2,WANG Hua-wen3,CUI Jian-zhong1(1.School of Materials Science and Metallurgy,Northeastern University,Shenyang 110004,China;2.School of Materials Science and Technology,Shenyang Ligong University,Shenyang 110159,China;3.Hunan ElectricityConstruction and Supervisor Consulting Co.,Ltd.,Changsha 410007,China)  
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 ℃.
