“…However, when Mg is present in levels greater than 3.5 wt%, Al–Mg alloys are susceptible to intergranular corrosion (IGC) and stress corrosion cracking (SCC) when exposed to elevated service temperatures (above 65°C) . Especially for high Mg content alloys, during sensitization treatment, the supersaturated Mg atoms are precipitated at the grain boundaries in the form of β‐phase (Al 3 Mg 2 , which is anodic relative to the Al matrix) and are continuously distributed, thereby making Al–Mg alloys are prone to IGC and SCC …”

The influence of strontium (Sr) additions in the form of Mg-Sr master alloys from 0 to 0.6 wt% on the mechanical properties, corrosive nature, and microstructure of Al-9.2Mg-0.7Mn alloys is investigated. The material is studied in a fully annealed (O-temper) and a sensitizing treatment at 150°C for 7 days. Here we demonstrate that there will be a new phase which might be (Al, Mg) 17 Sr 2 formed in the as-cast microstructure. When the Sr content is 0.2 wt%, under the premise that the mechanical properties of completely annealed alloy change little (relative to the matrix: the ultimate tensile strength increases by 8 MPa and the elongation only decrease by 1.6%), the intergranular corrosion resistance is significantly improved. The specific performance is that the mass loss from intergranular corrosion decreases by more than 53% from the addition of 0.2 wt% Sr after sensitizing.

“…The high quality plates can be used to manufacture containers, oil storage tanks, packaging boxes, train boxes, and so on. Since the rolling process is limited by total reduction ratio, rolling mill stiffness and rolling mill power, the central deformation of the plate is insufficient and the mechanical properties are difficult to meet the requirement of the consumers [1,2] . Then the asynchronous rolling is proposed to make the mechanical properties of the plate meet the requirements.…”

Asynchronous rolling can increase the shear strain, reduce the rolling pressure and save the energy, and achieve the goal of improving the quality of the plate and reducing costs. As a key factor influencing the quality of the plate, the effective strain is often obtained by experiments and numerical calculation, which is complex and time-consuming. Therefore, a theoretical calculation model for the asynchronous rolling is established. The deformation zone is divided into the rigid-plastic-rigid zone, and the flow function of the boundary condition is obtained by the principle of equal metal flow. Then, the rolling power model is established by the linearization integration method, which is the key to the theoretical modeling. The length of the top and bottom deformation zones can be obtained as unknown parameters by optimizing the power model. Finally, the effective strain is calculated according to the optimization results, so as to complete the establishment of the effective strain model. Based on the established model, it is proved by experiments and finite element method. Compared to the experiment results, the results show that the minimum and maximum relative errors are 1.38% and 8.89%. which can be accepted for production. The research can propose reference for actual production and improve actual production efficiency.

“…Compared to the limited studies on CS Al-Mg alloys, a large body of literature exists pertaining to the investigation of the corrosion properties of AA5083 processed by various manufacturing processes [29][30][31][32][33]. A couple of processing methods have shown the improved corrosion resistance of AA5083: the corrosion behavior of AA5083 produced by high-energy ball milling (HEBM) showed improved pitting resistance compared to its wrought counterpart due to the homogeneous microstructure that supported the formation of protective passive films [29].…”

“…A couple of processing methods have shown the improved corrosion resistance of AA5083: the corrosion behavior of AA5083 produced by high-energy ball milling (HEBM) showed improved pitting resistance compared to its wrought counterpart due to the homogeneous microstructure that supported the formation of protective passive films [29]. AA5083 modified by accumulative roll bonding (ARB) and conventional cold rolling (CR) were found to be resistant to IGC in an as-deformed condition based on ASTM G67, which was attributed to a favorable distribution of the β-phase [30]. AA5083 fabricated by additive friction stir deposition (AFSD) presented less pitting and IGC susceptibility in as-built conditions due to the refinement and redissolution of the Mn-rich secondary phase [31].…”

This paper investigates the effect of the microstructure on the corrosion behavior of cold sprayed (CS) AA5083 compared to its wrought counterpart. It has been shown that the microstructure of CS aluminum alloys, such as AA2024, AA6061, and AA7075, affects their corrosion behavior; however, investigations of the corrosion behavior of CS AA5083 with a direct comparison to wrought AA5083 have been limited. The microstructure and corrosion behavior of CS AA5083 were examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), electron backscattered diffraction (EBSD), electrochemical and immersion tests, and ASTM G67. The CS process resulted in microstructural changes, such as the size and spatial distribution of intermetallic particles, grain size, and misorientation. The refined grain size and intermetallic particles along prior particle boundaries stimulated the initiation and propagation of localized corrosion. Electrochemical tests presented enhanced anodic kinetics with high pitting susceptibility, giving rise to extensive localized corrosion in CS AA5083. The ASTM G67 test demonstrated significantly higher mass loss for CS AA5083 compared to its wrought counterpart due to preferential attack within prior particle boundary regions in the CS microstructure. Possible mechanisms of intergranular corrosion (IGC) propagation at prior particle boundary regions have been discussed.
