“…Al6061 consists mainly of aluminum, magnesium, and silicon. The other metallic elements include, in descending quantity order: iron, copper, chromium, zinc, manganese, and titanium [ 3 , 4 ]. Machining of aluminum alloys can be economically, effectively, and efficiently done because their machining properties are superior to those of pure aluminum due to the unique metallurgical structure [ 2 , 4 , 5 ].…”

Aluminum alloys are soft and have low melting temperatures; therefore, machining them often results in cut material fusing to the cutting tool due to heat and friction, and thus lowering the hole quality. A good practice is to use coated cutting tools to overcome such issues and maintain good hole quality. Therefore, the current study investigates the effect of cutting parameters (spindle speed and feed rate) and three types of cutting-tool coating (TiN/TiAlN, TiAlN, and TiN) on the surface finish, form, and dimensional tolerances of holes drilled in Al6061-T651 alloy. The study employed statistical design of experiments and ANOVA (analysis of variance) to evaluate the contribution of each of the input parameters on the measured hole-quality outputs (surface-roughness metrics Ra and Rz, hole size, circularity, perpendicularity, and cylindricity). The highest surface roughness occurred when using TiN-coated tools. All holes in this study were oversized regardless of the tool coating or cutting parameters used. TiN tools, which have a lower coating hardness, gave lower hole circularity at the entry and higher cylindricity, while TiN/TiAlN and TiAlN seemed to be more effective in reducing hole particularity when drilling at higher spindle speeds. Finally, optical microscopes revealed that a built-up edge and adhesions were most likely to form on TiN-coated tools due to TiN’s chemical affinity and low oxidation temperature compared to the TiN/TiAlN and TiAlN coatings.

“…Heat exchangers, hospital equipment, automotive parts, etc. are made of aluminum alloy 3105 [11], while the 2024 aluminum alloy is utilized in the manufacture of airplanes, fuel tanks, auto parts, and other machinery [12]. The aluminum alloy 5083 is frequently used in marine equipment, pressure and storage tanks, constructions, and aircraft sectors, but in situations with a lot of power requirements, 7075 aluminum alloy is employed [13].…”

Amorphotheca resinae is a fungus that particularly corrodes aeronautical aluminum alloys, leading to economic issues in various industries. This study aims to investigate the effects of this fungus on the corrosion of four different aluminum alloys, namely 2024, 7075, 5083, and 3105, after 25, 50, and 75 days through scanning electron microscopy (SEM), confocal laser scanning microscopy (CLSM), 3D profilometry, weight loss (%) measurement, energy dispersive spectrometry (EDS), electrochemical impedance (EIS), and pH changes. After 25 days, the 2024 alloy had the highest mycocorrosion rate (1.3417 mpy), while alloy 3105 had an undetectable value on this day. According to the EIS test, the 3105 alloy had the highest level of resistance (1.12×105 Ω.cm²) to corrosion, while the 2024 alloy was the most susceptible (7138 Ω.cm²). The qualitative data from SEM, CLSM, and 3D profilometry also confirmed the quantitative findings where the surface pits on the 2024 alloy were deeper than those of other alloys. Overall, the results showed that the lowest and highest corrosion rates mediated by A. resinae belonged to 3105 and 2024 alloys, respectively. These findings could have significant implications for industries that use aluminum alloys and might help in developing strategies to prevent or control biocorrosion.

“…Because of a series of advantages such as low density, high specific strength, high corrosion resistance, easy thermal and electrical conductivity, low cost, good plasticity and processing properties, aluminum alloys are widely used in aviation, automobiles, high-speed trains and other fields [1,2]. Compared to other metals, aluminum alloys have more excellent plastic deformation properties.…”

In order to study the mechanical properties of aluminum alloy, this paper adopts the birth-death element method (BDEM) to numerically analyze the behavior of tensile cracking of aluminum alloy specimens. A finite element model was established using Abaqus, and the BDEM were set in the deformation region. The results show that the BDEM accurately simulates the cracking behavior of the aluminum alloy. The specimen began to fracture when the experimental time was 18 s. The maximum Mises stress during the whole tensile process is 445.3 MPa. Compared with the traditional mechanical experiments, this method can obtain the stress/strain data during the large-scale plastic deformation of the aluminum alloy before rupture, which provides data support for the design and optimization of aluminum alloy parts.
