“…The bigger the pre-bending force, the more obvious the phenomenon. For the plastic material of 6061Al without an apparent yield stage, the stress when plastic strain is 0.2% is usually used as the yield limit stress [ 22 ]. After pre-bending force is loaded, the ability of material to resist elastic deformation increases.…”

In order to realize a micro-mechanic performance test of biaxial tensile-bending-combined loading and solve the problem of incompatibility of test apparatus and observation apparatus, novel biaxial-combined tensile-bending micro-mechanical performance test apparatus was designed. The working principle and major functions of key constituent parts of test apparatus, including the servo drive unit, clamping unit and test system, were introduced. Based on the finite element method, biaxial tensile and tension-bending-combined mechanical performances of the test-piece were studied as guidance to learn the distribution of elastic deformation and plastic deformation of all sites of the test-piece and to better plan test regions. Finally, this test apparatus was used to conduct a biaxial tensile test under different pre-bending loading and a tensile test at different rates; the image of the fracture of the test-piece was acquired by a scanning electron microscope and analyzed. It was indicated that as the pre-bending force rises, the elastic deformation phase would gradually shorten and the slope of the elastic deformation phase curve would slightly rise so that a yield limit would appear ahead of time. Bending speed could exert a positive and beneficial influence on tensile strength but weaken fracture elongation. If bending speed is appropriately raised, more ideal anti-tensile strength could be obtained, but fracture elongation would decline.

“…In their study, Liu et al took 6013 aluminum alloy samples into the solution at 560 °C for 2 hours, then artificially aged them at 191°C and different periods between 10 min-24 h, and examined their mechanical properties. The highest hardness value was measured as approximately 111 HV in the sample aged for 4 h. They also found the highest yield and tensile strength in this sample to be 258 and 310 MPa, respectively [14].…”

In this study, the effect of artificial aging parameters, applied to AA6013 aluminum alloys commonly used in the automotive and aerospace sectors, on wear resistance was examined. For this purpose, AA6013 aluminum alloy samples were solutionized at 575 °C for 60 minutes and then they were artificially aged for 2, 4, and 6 hours at 180 and 200 °C temperatures. Mean hardness was measured as 66.6 HV in the solutionized samples taken. It was determined that as a result of artificial aging, α-AlFeMnSi intermetallic phase precipitation were formed between α-Al grains. By the effect of precipitation hardening, an increase in hardness was observed in all artificially aged samples; the highest hardness was found as an average of 149.3 HV in AA6013 samples aged artificially for 2 hours at 200 °C. A general decrease in the friction coefficients of samples aged at both 180 °C and 200 °C was observed along with the artificial aging temperature. The lowest specific wear rate was determined as 3.542x10 -3 mm 3 /Nm in the AA6013 sample aged artificially for 2 hours at 200 °C.

“…The dislocation density calculated in present work is similar to that of some studies on plastic deformation of aluminum alloy. For example, Liu et al [25] obtained the dislocation density of ECAP 6013 aluminum alloy at different temperatures as 1.2-1.7 × 10 14 m −2 through XRD diffraction. Schiller et al [26] measured the dislocation density of ECAP 7000 series Al alloys at 200 • C by XRD to be 3.4 × 10 14 m −2 .…”

7075Al alloy is the preferred material for lightweight automotive applications, but the existing problem is that it is difficult to combine high strength and high toughness. This paper presents our research aimed at obtaining high strength and high toughness materials by adding a nano-phase to realize microstructure refinement. Graphene nanoplates (GNP)/7075Al composites and 7075Al alloy were prepared by a stirring casting method in the present study. In comparison to 7075Al, the tensile strength of GNP/7075Al composites was increased from 572 MPa to 632 MPa while maintaining good uniform elongation of 8% to 10%. The increased strength behavior of GNP/7075Al composites while maintaining the plasticity is discussed in terms of grain refinement and dislocation evolution by analyzing the composite microstructure and quantitatively analyzing the contributions of grain boundary strengthening, solid solution strengthening, precipitation strengthening and dislocation strengthening. GNP’s strengthening of GNP/7075Al composites is mainly attributed to the refinement of grain size and the increase of dislocation density.
