Aluminum stress affects three aspects: First, stress factors, including different loads processing, load size, loading direction, load speed, on the SCC, the stress must be perpendicular to the grain boundaries, in order to be able to separate them. The key factor is stress corrosion stress. And the different stresses may produce different results, alternating stress and environmental corrosion fatigue, stress generated from it, and secured together, produce is usually significantly different stress corrosion cracking. General corrosion fatigue stress corrosion than the more serious consequences. In addition, will also affect the loading speed of different susceptibility to stress corrosion of aluminum. Second, environmental factors, stress corrosion effects of aluminum are: ion species, ion concentration, pH, oxygen and other gases, corrosion inhibitors, ambient temperature, ambient pressure. Different atmosphere 2A12 and 7A04 two stress corrosion of aluminum, aluminum alloy was found to have a different sensitivity to emphasize corrosion in the marine environment is more sensitive to the marine environment contains a lot of salt, chloride ions will pass into the interior in a different environment aluminum luggage rack factory protective film, the reason the corrosion of aluminum surfaces. Third, metallurgical factors include casting method, processing method and thermal stress corrosion gold, found an increased susceptibility to cathodic polarization, aluminum alloy friction stir welding stress corrosion susceptibility to stress corrosion lower than welding. Generally believed that, after appropriate treatment of aluminum alloy 6061-T6,3004 not appear SCC. Metallurgical factors in different ways to change the type of aluminum paper mask and cause different changes within the organization and the crystal structure of aluminum, thus affecting the electrochemical behavior and mechanical behavior of aluminum, resulting in stress corrosion susceptibility of different aluminum alloys. Aluminum product quality is good or bad by what factors? The quality of every product is good or bad will be affected a variety of factors, small series, and we elaborate below under the aluminum product quality is affected by what is good and bad factors. 1, by the impact of production technology, production equipment, the quality of workers and other factors. 2, in the different production standards and product quality specifications and therefore will be affected differently. 3, some of the treatment process and test items aluminum products, if there is no demand-side CNC precision machining requirements, supply-side processing is not provided radiator fins processing, so the product can cause significant performance differences. Such as Alcoa products may have to undergo a series of heat strengthened alloy internal stress elimination process, ultrasonic flaw detection, spectroscopy, semiconductor bending tests, microscopic corrosion test, electromagnetic (eddy current) test, and cracking susceptibility testing and other projects, to ensure that all aspects of Alcoa products in the market are outstanding. 4, deformation of aluminum or aluminum alloy grades figures represent the average percentage of maximum purity or an alloy of some chemical elements. 5, even if the chemical composition, the same brands of products are based on its production standards and the production of different batches differ.
