Description
Technical field
The present invention relates to a kind of metallic material corrosion Test And Check Technology, particularly a kind of environmental device that axially loads the high temperature stress corrosion test for metal material.
Background technology
Metal material has the possibility that delayed fracture and fracture occur voluntarily under tension and specific media environment double action.The low stress corrosion brittle failure that it produces has unpredictable character, usually causes the generation of accident and the loss of lot of materials, uses to engineering and has brought great potential safety hazard and property loss.For this reason, the stress corrosion crack problem of metal material is the key areas of material antiseptic and safe and reliable Journal of Sex Research, and stress corrosion (cracking) test is the important foundation of stress corrosion research, its result's accuracy directly affect engineering reliably whether.
At present, the metal material stress corrosion (cracking) test of carrying out both at home and abroad, mainly be that metal material processing is become specific sample (such as tensile sample, C type sample, bend specimen etc.), place specific simulated environment medium (such as seawater, fluidizing chlorination magnesium solution, water vapour), and by charger sample imposed load (constant stress, constant strain and slow strain rate) is tested.Relevant standard mainly contains GB15970 series, ASTM G49 and YB5362.For charger, mainly purchase from the market at present the lasting machine of ready-made dead load or slow strain rate test machine; For environmental device, each unit carries out designed, designed according to the test objective of oneself.In the standard, design for environmental device has only provided rough schematic, do not further specify and how to design and to prevent the seepage of corrosive medium/leakages in (the general time of stress corrosion (cracking) test is all long) process, to keep the constant of medium temperature and concentration in test, and these are no matter security or accuracys that collateral security is tested are all extremely important.For normal temperature or the low temperature stress corrosion design with the media environment device, the problems referred to above also are easier to avoid, because 1. the problem of seepage can be carried out encapsulation process to sample and environmental device binding site by silicon rubber and solved; 2. when low temperature was tested, resistance wire working time interval was large, long service life, joined the higher temperature control system of a cover precision, just the requirement of energy warranty test temperature; 3. the water in the medium volatilizees slowlyer in low temperature environment, and the water that regularly replenishes volatilization in the media environment device is to initial metal line (generally once a day), just the concentration of control medium effectively.And for the design of the environmental device that is used for the high temperature stress corrosion test, particularly be used to up and down the axial loading stress corrosion of wearing with the design of environmental device, the problems referred to above make the testing crew headache always.This be because: the ⑴ leakage problems: silicon rubber or other glue sealing effectiveness in hot environment weaken, and seepage/leakage phenomenon often occurs, cause the testing equipment corrosion, and process of the test is also very dangerous.⑵ temperature constant problem: resistance wire only works long hours even continuous working (such as the stress corrosion (cracking) test of fluidizing chlorination magnesium), guarantee high-temperature medium temperature constant, therefore be easy to burn out, as can not in time changing or keep in repair, will cause testing non-normal termination; ⑶ constant concentration and the medium problem of splashing: the water in the medium volatilizees when high temperature comparatively fast, supplementing water in the medium automatically and continuously, and on the one hand wayward magnitude of recruitment and the balance of waving the method amount, it is constant that concentration is difficult to keep; Also be prone on the other hand water at low temperature and add the phenomenon that medium that high-temperature medium causes splashes, process of the test is very dangerous.
