Grain Growth Model of AZ80 Magnesium Alloy Under Isothermal Condition

摘要：

　　Microstructure evolution of AZ80 magnesium alloy under isothermal condition is researched by experiment.Effect law of heating temperature and holding time on grain size for AZ80 magnesium alloy is researched.With increasing of holding time and with rising of heating temperature,the grain size increases obviously.According to the test data,the grain growth model of AZ80 magnesium alloy under isothermal condition is established based on Sellers model,and the activation energy of grain growth of AZ80 magnesium alloy is determined,Q=85900J/mol.The model calculation results are in good agreement with that of experiment,and the relative errors between the model calculation results and that of experiment are less than 15.6%.
