This paper presents results of monotonic tensile and creep tests conducted on typical Al-Cu-Mg alloy (commercial 2024) specimens. Tensile tests carried out at room (20 • C) and elevated (100 • C, 200 • C, 300 • C) temperatures made it possible to determine strength properties of the material (Young's modulus, yield stress, ultimate tensile strength). Creep tests were performed at elevated temperature (100 • C, 200 • C and 300 • C) with a constant force. In order to obtain material creep characteristics, creep-rupture tests were carried out. Then creep tests were conducted with two different strain values: one corresponding to the beginning of the secondary creep and the other corresponding to a certain value of the tertiary creep. After preliminary creep deformation at two various strain levels, specimens were cooled at ambient temperature and then subjected to monotonic tensile tests. The characteristics of the material were obtained for pre-strained specimens at different temperatures. Specimens fracture surfaces obtained as a result of tensile (at elevated and room temperature), creep and combined tests were analyzed.

“…The dynamic tensile fracture (or spall) behaviours of metallic materials produced by the interaction of release waves after shock loading is a complicated physical process that can be strongly influenced by many variables related to the applied loading, temperature, and the material itself . A number of researchers have studied how the spall behaviour of materials depends on the loading conditions . In fact, accurate determinations of these microstructural effects on a material's spall behaviour are important for the development of structure‐property correlations, better alloy design for improved properties, and predictive material damage models.…”

The effects of grain size on the spall response were investigated for high purity copper materials by plate-impact experiments including real-time measurements of the free surface velocity profiles as well as post-impact fractography studies on the soft-recovered samples. High purity copper plates were cold rolled and heat treated to produce recrystallized samples with average grain sizes of 78, 273 and 400 μm, respectively. The spall strength estimated from the free surface velocity profile is nearly constant with no significant effect on the grain size. However, differences are observed in the acceleration rate of velocity rebound beyond the minima. This may be attributed to the effect of grain size on the growth rate of damage. Metallographic analyses of the fracture surface show that the characteristic feature of the fracture surface clearly depends on the grain size. In the 78-and 273-μm samples, the fracture surfaces are decorated with large, high-density ductile dimples suggesting that the preferential failure mode is ductile intergranular fracture. In the 400-μm samples, the fracture surfaces have a rock candy appearance with small, high density brittle dimples as well as large ductile dimples suggesting that the fracture mode is a mix of both brittle intergranular fracture and ductile transgranular fracture.

“…Also, MacMaster and colleagues obtained the fracture toughness of 6061-T6 Al alloy as 48.7 [33]. Lastly, Wang et al revealed that the 7075-T6 Al alloy has a fracture toughness of 33 [34]. The experimental findings in the literature were utilized as reference values, and Figure 7 was generated.…”

This research experimentally compared the correlations between fracture toughness and Charpy V-notch tests.The fracture toughness tests are expensive, complex, and laborious. Therefore, researchers developed correlations to estimate fracture toughness using Charpy V-notch tests, thereby structural integrity assessment. For the current work, nine different fracture toughness correlations were selected using the existing literature, and most common Al alloys, including 2024-T4, 6061-T6, and 7075-T6, were chosen as testing materials. Tensile tests were utilized to determine the deformation behavior of the tested alloys. Also, Charpy V-notch tests were carried out to obtain absorbed energy during the low impact conditions. Rupture strain, yield, and ultimate tensile strengths of the alloys were determined by tensile testing. Charpy V-notch test results revealed that the energy absorption ability of the 6061-T6 Al alloy is roughly two times higher than the 2024-T4 and roughly four times higher than the 7075-T6 Al alloy. The fracture toughness estimations resulted in a broad range of values. The experimentally obtained fracture toughness values attained from the literature were used to define the error of each correlation. One of the tested correlation yielded the lowest average error with an error percentage of 15.6%. Lastly, the ductile fracture of the 6061-T6 Al alloy tensile test specimens executed at the quasi-static conditions was attributed to having a higher fracture toughness.
