“…Dwivedi et.al, [16] concluded that when addition of reinforcements such as SiC, Al2O3, TiC, B4C, SiO2, and iron powder in the micro or nano-size can change the microstructural features that leads to good physical and mechanical qualities in the alloys particularly for aerospace applications. Pandouria et.al, [17] in his study concluded that as the temperature increases up to 200 °C the flow stress decreased gradually and beyond that it is reduces surpassingly. Moreover, when the temperature rises from 25 °C to 250 °C, the true fracture strain increased from 14.8 to 51.5%.…”

AA2014 is most widely used metal among the aluminium alloy series due to its exceptional corrosion resistance, low density rate, and it can maintain high strength and toughness at various temperatures. So, these materials have their application in the aerospace, military and the automotive sector. The present work focuses on evaluating the mechanical properties such as ultimate Tensile strength (UTS), Yield strength (YS), and percentage of elongation using Uniaxial Tensile test. The three controllable factors used in the present study are temperature ranging from 200 to 300°C with 50°C increment, orientation 0,45,90 degree relative to the rolling direction and strain rate 0.001,0.01 and 0.1mm/sec. A total of 27 experiments were planned and conducted based on the design of experiments. Experimental results show that with increase in strain rate increasing of material properties furthermore with increase in temperature decrease of material properties and increase in the percentage of elongation was observed. In addition to that ANOVA analysis was carried out and noticed that strain rate is most effecting parameter for UTS and temperature is most effecting parameter for YS and percentage elongation. The fracture specimens from uniaxial test are investigated for type of fracture through microstructural studies

“…However, Verlinden et al [8] have confirmed that even after a long homogenization or solid solution treatments, Al 2 Cu and Al 2 CuMg remain in the residual second phases in 2024 series aluminum alloys. Several studies have shown that the second phase can adversely affect the fracture toughness values for aluminum alloys [9,10]. However, the residual second-phase fracture behavior has yet to be investigated in 2024 aluminum alloys.…”

In this study, a special fracture delamination in L-T fracture toughness specimens of an Al-Cu-Mg alloy was researched by applying three-dimensional optical microscopy (OM), scanning electron microscopy (SEM), and electron backscatter diffraction (EBSD) methods. The results indicate that the fracture delamination is contributed by the cracks extending a long distance in the T-direction and extending internally along the L-direction, which can result in a lower fracture toughness value. The fracture delamination is determined by the level of grain flattening and the distribution of the second phases. The flat grains result in a tendency for cracks to extend in the T-direction. At the same time, the unevenly distributed Al2Cu and Al2CuMg phases lead to cracks extending in the L-direction, which eventually causes the formation of delamination fractures. The reduction in grain size can also contribute to weakening the fracture delamination to a certain extent.

“…Aluminium alloys are a widespread, effective material with a long history of successful use in a variety of industries, notably in aircraft, marine, railway, and automotive applications. Because of its flexibility, strength, high durability, and great resistance to corrosion [1,2]. Due to their high strength, aluminium alloys from the series 2XXX and 7XXX are appropriate for use in the production of airplane parts, and throughout the course of their service life, the mechanical components of these alloys are regularly subjected to complicated loadings [3].…”

The main objective of this study is to experimentally determine the fatigue life of the aluminum alloys AA2014 and AA7075-T651 by measuring the lengths of short and long cracks practically under bending stress with constant amplitude loading and stress ratio (R = -1) at room temperature (RT) 25 C0 by employing Basquin's equation. To determine the fatigue life curve for both alloys at five different levels of constant amplitude stresses, the average failure cycles of three specimens at each stress level were recorded. The surface of specimen was replicated with cellulose paper and liquid acetone. This piece was examined using an optical microscope to record the length of the crack and the number of cycles corresponding to it at a constant stress level. The lengths of the cracks were then measured using the replication approach. A unique mathematical model was created to describe the relationship between crack speed (da/dN) and the length of short and long cracks in order to predict the overall fatigue life of each alloy. When the model's result was contrasted with actual outcomes, the conclusions were reliable and productive.
