【Abstract】 Objective To study the material cracking time of stress corrosion. Methods Theory of environmental effect dynamics was applied to solve the function of the material cracking time of stress corrosion. Results The function of the material cracking time under stress corrosion was acquired from the theory of environmental effect dynamics. In addition, an experimental verification was carried out to AZ61 and AZ80 magnesium metal alloy. Conclusion The theory of environmental effect dynamics can be used to describe the material cracking time of magnesium metal alloy under stress corrosion; the anti- stress corrosion function of AZ61’s surpasses that of AZ80.更多还原
