In this paper, the influence of the solution aging process on the mechanical properties and electrical conductivity of Al-0.6Mg-0.45Si-0.07B-0.05Re pipes was explored. Through the research on the solution aging process, it was found that the aging temperature had the greatest influence on the tensile strength of the material, and the aging time had the least influence. The aging temperature has the greatest impact on the material’s electrical conductivity, while the solution temperature has the least. The aging temperature has the greatest impact on the material’s electrical conductivity, while the solution temperature has the least. By analyzing the STEM of aluminum alloys aged at 170 ℃/12 h and 200 ℃/12 h, it was found that low-temperature aging would produce a wider PFZ range, reducing the material’s electrical conductivity, and at the same time generate smaller-sized and more numerous precipitated phases, thereby enhancing the material’s strength.

In this paper, TC6 titanium alloy was subjected to solution treatment at different temperatures to study the microstructure evolution and tensile properties of TC6 titanium alloy after solution treatment. It was found that the solution temperature played an important role in the microstructure. With the increase of the solution temperature, the atomic diffusion rate of the primary α phase was accelerated, and it was continuously transformed into the β phase, resulting in a gradual decrease in its content, while the content of the precipitated α' phase in the structure was increasing. In this process, the strength of the alloy increases while the plasticity shows a decreasing trend, indicating that the plastic deformation ability of the alloy will continue to weaken during the strength increase process. When the solution temperature is low, the tensile fracture shows a typical dimple structure, and there is a significant toughness behavior during the fracture process. With the increase of solution temperature, the dimples in the tensile fracture become thinner and smaller, and the alloy gradually tends to brittle fracture.

The internal residual stress of magnesium alloy plates will reduce their deformation performance and at the same time bring adverse effects such as non-uniformity and inconsistency to the mechanical properties of the product. Estrusion-rolling technology, reversing rolling technology, asynchronous rolling technology, rare earth or microalloying technology can all reduce the internal residual stress of magnesium alloy plates to a certain extent. The influence of deformation temperature and compression ratio on the residual stress of magnesium alloy plates is relatively obvious in the traditional production technology field, but under the conditions of this study, its influence is limited.

In order to explore the causes of the point scratch defect on the surface of C19400 copper alloy, by inspecting and analyzing the surface quality of the precious and subsequent processes, it was determined that the point scratch occurred in the cold finishing process of the product. Further verification was made that poor lubrication of the rolling oil was the main cause of the point scratch on the surface of the strip, and rectification measures were proposed.

Aiming at the problems of poor adaptability to industrial scenarios and insufficient detection accuracy in the detection of surface defects of copper strips, this paper studies and designs a multi-module collaborative online detection system for surface defects of copper strips. The system determines the operating status of the slitting unit in real time through the HSV color space segmentation algorithm and constructs a multi-index image quality evaluation model based on the entropy method-TOPSIS method. Images of three types of typical defects (scratches, peeling, black lines) were collected on-site in the 600mm slitting unit and a dataset was constructed. The YOLOv11 AND Faster R-CNN detection models were established respectively for comparative study. Experiments show that the mAP50 of the YOLOv11 model on the test set reaches 77.5%, which is significantly better than 58.3% of the Faster R-CNN model. Industrial verification shows that after the system was deployed, the defect detection deviation was controlled at around 25 in the morning and evening. Research has confirmed that this system, through multi-index quality evaluation adaptive optimization mechanisms, has achieved high-precision online detection of surface defects in copper strips under complex working conditions, demonstrating significant engineering application value.
