“…The self-corrosion potential of the Al-Cu-Mg-Ag alloy was evaluated using PFZ, and it was found that EPFZ < Eq < EMatrix. By adjusting the grain boundary microstructure, T614 temper can significantly enhance the exfoliation corrosion resistance of the alloy [27]. Intermetallic particles found in aluminum alloys have a significant impact on the breakdown of the passivity and pit morphology of these alloys when exposed to seawater.…”

The present study aimed to investigate the influence of magnesium (Mg) on the mechanical properties and corrosion behavior of wrought Al–4Cu–xMg–0.6Ag alloys. The results from Optical Microscope, SEM, XRD analysis, and Thermo-Calc simulation were used to identify the microstructure formed after the aging process. Testing for hardness and tensile strength was conducted, in addition to corrosion testing. It was found that Mg significantly impacts the hardness of the alloys, with a high Mg content (low Cu/Mg ratio) increasing the hardness but reducing the tensile strength and ductility. This study attributed this to the formation of the S phase, which is dependent on both the quantity in the bulk and the size of the phase. The grain size was found to be finer with a higher Mg content, since the particle size inhibits grain growth during the artificial aging process. Counterintuitively, the corrosion activity was reduced in the high-Mg-content alloy due to its large particle size and the reduced galvanic cell effect. This study highlighted the importance of considering the effects of Mg on the mechanical properties and corrosion behavior of Al–Cu–Mg–Ag alloys.

Corrosion failure is a thorny issue that restricts the applications of Al alloys. As a research hotspot in functional realization, hydrophobic fabrication exactly offers an efficient method to settle metallic corrosions. This work has developed a facile and low-cost method to enhance corrosion resistance of Al alloys. The micro-nano dendrites have been firstly prepared on metallic substrate using one-step potentiostatic deposition. Then, wetting and electrochemical behaviors have been systematically investigated after stearic acid modification. Results show that the as-prepared surface possesses amplified and durable water repellence with an apparent contact angle (CA) of 154.2° and a sliding angle (SA) of 4.7°. Meanwhile, owing to the trapped air in dendrites, the newly-generated solid-air-liquid interfaces help to resist seawater penetration by reducing interfacial interactions on the super-hydrophobic surface as well as significantly enhance its corrosion resistance. This work sheds positive insights into extending the applications of Al alloys in many areas, especially for ocean engineering fields.

“…Al-Si alloys are widely used in the aerospace, military, and automobile industries due to their superior castability and good balance of strength, ductility, and corrosion resistance. [1][2][3][4] However, under the conditions of traditional casting processes, Al-Si alloys usually contain massive coarse, or long needle or lamellar shape eutectic Si phases, which degrades the microstructure of alloy, and reduces the mechanical properties and decreases corrosion resistance. 5 The addition of rare earth (RE), Sr, Al 2 O 3 or ceramic elements, and the heat treatment 6 is an effective way to change the morphology and distribution of eutectic silicon phase in Al-Si alloys.…”

Aluminum matrix composites reinforced with SiC particles (SiC p) were prepared by electromagnetic stirring. This article aims to study the effects of SiC p addition on microstructure and mechanical properties of SiC p /ZL105, finally leading to expended range for ZL105 alloy application. Microstructural studies were carried out by optical microscope, scanning electron microscopy, and energy dispersive spectrometer. Tensile and hardness tests were conducted in order to identify mechanical properties. It was found that addition of 1.5 wt% SiC p causes the refined microstructure (including primary a-Al and eutectic Si) and reduced secondary dendrite arm spacing of a-Al matrix (12.6 mm). Compared to the ZL105 alloy, the ultimate tensile strength, elongation, and hardness of the composite with 1.5 wt% SiC p were increased by 24.6%, 37.3%, and 27.0%, respectively. The improved mechanical properties can mainly be attributed to the refinement of primary a-Al and eutectic Si, and uniformed dispersion of SiC p. Furthermore, the effects of voltage and agitation frequency of magnetic field on microstructure of composites were discussed.
