Abstract

The invention discloses a tiny sample stress corrosion experimental device and a tiny sample stress corrosion experimental method. The tiny sample stress corrosion experimental device comprises a stress loading mechanism used for applying loads to a sample, a support used for containing the sample, a corrosion container, a thermostatic water bath and a deflection measuring device used for measuring the deformation of the sample, wherein the support is arranged in the corrosion container, and the thermostatic water bath is used for controlling and adjusting the temperature in the corrosion container. According to the tiny sample stress corrosion experimental device and the tiny sample stress corrosion experimental method, tiny sample constant load experiments in a corrosive environment are implemented, accuracy and effectiveness of the experiments are ensured, the service conditions of equipment in service are learnt in advance through the experiments, and thus heavy economic losses and personal casualties can be prevented.

Description

technical field [0001] The invention relates to a micro-sample stress corrosion test device and a micro-sample stress corrosion test method. Background technique [0002] Under the action of stress, metal materials may undergo stress corrosion cracking in a specific corrosive environment. This kind of brittle fracture without warning under low stress will lead to huge economic losses and casualties. In industries with high energy consumption such as thermal power, nuclear power, petrochemical and oil refining, how to ensure the safe and stable operation of related equipment in corrosive environments has become a major research topic. For example, in the equipment of petrochemical enterprises, 41.6% of the corrosion failures are stress corrosion. Under certain working conditions, there is a certain interaction between the load action and the corrosion environment, which affects the service life and safe operation of the equipment in service. Therefore, it is necessary to ful...
