Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0036] Based on the above purpose, an embodiment of the present invention proposes a method for measuring tensile stress corrosion of deformed aluminum alloys, which can quantitatively measure the stress corrosion sensitivity of aluminum alloys.
[0037] A method for measuring tensile stress corrosion of deformed aluminum alloy provided by the invention comprises the following steps:
[0038] Remove the aluminum-clad layer on the surface of the sample;
[0039] The stress corrosion susceptibility is measured by the relative change of the same mechanical parameters of the same specimen exposed to the comparative test environment and to the inert environment;
[0040] The stress corrosion susceptibility is expressed as:
