In-situ annealing experiments were performed in the scanning electron microscope on a single-phase Al-0.13Mg alloy cold rolled to different strain levels. Once the validity of the technique had been verified by comparison of the recrystallization kinetics and final grain size with bulk annealed samples, the method was used in combination with electron back-scattered diffraction (EBSD) to study the potential mechanisms for recrystallization in this alloy. During annealing of material rolled to moderate strains (epsilont < 0.7), the primary mechanism was strain-induced boundary migration (SIBM). In material rolled to higher true strains (epsilont > 1.4), recrystallization occurred extensively along pre-existing cube bands and EBSD measurements showed that the mean size of cells within the cube bands was larger than for all other orientations measured, suggesting a size advantage was responsible for the strengthening of cube texture during recrystallization. SIBM was shown to occur concurrently with the nucleation along cube bands but this contributed a lower proportion of nucleation sites during recrystallization.

| Surface Roughening Behavior of 6063 Aluminum Alloy during Bulging by Spun Tubes |

Aluminum alloy has played an important role in lightening automobiles with hydroformed aluminum tubes making it possible to create lightweight parts with spatial structures and complex sections that can replace steel in high-end cars, and achieve energy savings and emission reductions. The first aluminum alloy rear axle subframe made by hydroforming was used in the 5-series BMW(Bayerische Motoren Werke), with its total weight of only 11.5 kg achieving a significant weight reduction when compared to steel . Audi have since manufactured roof rails by hydroforming 6014 aluminum alloy and used these in their A2 and A8 series vehicles to reduce their body weight by 40%
Surface roughening occurs on the surface of aluminum alloy tubes during hydroforming deformation, and when the surface roughening is severe enough, it produces surface defects such as “orange peel” or ridging and roping that affects the industrial production negatively [9,10,11]. It is widely accepted that such materials have an anisotropic behavior and different crystal orientations, which leads to incompatibilities of deformation arising from interactions between neighboring grains. The surface roughening behavior attributable to the deformation of individual grains can generally be observed on a grain scale , and so the most basic influential factors include internal factors (mainly grain size) and external conditions (mainly strain) .
The factors that influence surface roughening have mostly been investigated through tensile deformation, bending experiments and also cup drawing tests . Under a uniaxial stress state, the surface roughness first increases then decreases slightly with increasing strain, but increases linearly with increasing grain size [15,19]. Other studies have found that the surface roughness increases linearly with both increasing grain size and strain [17], but very few reports have paid attention to surface roughening under biaxial stress conditions. One study investigated the relationship between surface roughness and strain using numerical simulation, but this was neither verified by relevant experiments, nor did it consider the relationship between microstructure and surface roughness of tube during hydroforming .
In this study, bulging tests were carried out using 6063 aluminum alloy tubes with different microstructures to determine the quantitative relation between surface roughness, strain and grain size under biaxial stress. For this, tubes with different grain sizes and textures were prepared by spinning and annealing, and different strains were obtained by changing the area of the bulged tube. Measurements of surface roughness and observations of surface topography were also carried out using a confocal scanning laser microscope. Microstructural information was obtained using electron back-scattered diffraction (EBSD).

6063 aluminum sheet is one of the most commonly used aluminum sheet in the 6000 series aluminum sheet. The 6000 series aluminum sheet is an extruded alloy with Al-Mg-Si element added. At present, more than 70% of the aluminum extrusion processing material in the world is made of the alloy of the 6000 series. The common state of 6063 aluminum sheet includes O state, T4 state, T6 state and T651 state. The alloy of T651 state is formed after stretching and eliminating internal stress on the basis of the T6 state, which is more suitable for processing molding.
6063 aluminum alloy plate are widely used in building aluminum doors and windows and curtain wall framework, in order to ensure that the doors and windows, curtain walls with high wind resistance performance, assembly performance, corrosion resistance and decorative properties, requirements for the comprehensive performance of aluminum alloy profile is much higher than the industry standard sections.

Why does the aluminum plate have to wake up before it can wake up the anodic oxidation and do the electrolysis directly in the solution, how is the oxidation anode treatment in the dilute sulfuric acid? When do we need to use high-voltage power to process?
I actually ask one of the aims of this group, that is to think about the comprehensive study of the technology and technology of the West. I do not know who can help me to introduce the related technology of aluminum oxidation plant. I hope to be able to learn the skills of the teachers, and do not know how to get more information, and compare the information on the website of that enterprise. How much more? Ask the master to recommend several websites worth paying attention for a long time.
In the anode surface treatment industry, many manufacturers are just making material only for processing, higher technical requirements, such as this factory does not do industrial integration, it will inevitably collapse, because the characteristics of this period is not high profit, belong to the processing industry, in many aspects of the growth of enterprises, mainly It is difficult to carry out the production activities, the profit is a boy and a baby, in fact, it is also difficult, mainly depends on the way factory owners improve their profits, strengthen the expansion and construction of the internal and external parts of the factory. Especially in the situation of economic downturn, we should pay more attention to the trend of the oxidation industry. There are few inadvertently likely to turn over the car, and there is a certain risk of bankruptcy.

Sulfuric acid dilute sulfuric acid is a non oxidizing inorganic acid. It has slight chemical etching effect on aluminum alloy profiles, and has low use cost and less volatile acid fog. Sulphuric acid can dissolve and peel off the natural oxide film formed on the surface of aluminum and aluminum alloy, and the exposed aluminum alloy matrix reacts with sulphuric acid to activate the surface of aluminum. When the concentration of sulphuric acid in the bath is less than 30%, the chemical dissolution rate of aluminum increases slowly with the increase of sulphuric acid concentration, and the loss of aluminum is less. When the concentration of sulphuric acid exceeds 30% in the bath, the corrosion rate of aluminum accelerates rapidly, and it is easy to produce corrosion and decrease the brightness. Generally speaking, the concentration of sulfuric acid in the bath should not exceed 15%.
