Tensile properties and microstructure of 2024 aluminum alloy subjected to the high magnetic field and external stress

Abstract: In order to explore the dependence of plasticity of metallic material on a high magnetic field, the effects of the different magnetic induction intensities (𝐻 = 0 T, 0.5 T, 1 T, 3 T, and 5 T) and pulses number (N = 0, 10, 20, 30, 40, and 50) on tensile strength (σ b ) and elongation (δ ) of 2024 aluminum alloy are investigated in the synchronous presences of a high magnetic field and external stress. The results show that the magnetic field exerts apparent and positive effects on the tensile properties of th… Show more

“…After the processes, the content of the primary alpha phase in the alloy was increased, and the dislocation entanglement was decreased. Li et al [23] studied the influence of an electromagnetic field on the aluminum alloy mechanical properties and microstructure. The pulse magnetic field can induce cyclical shocks in molten metal.…”

“…Being different from the normal of tensile test without extra stress, the sample was exposed synchronously to the tensile stress and magnetic field generator and the sample should be ensured to be parallel to the direction of magnetic induction lines. [9] The testing machine is DNS10 electronic universal one with 10-kN maximum loading force. In order to prevent the force of HPMF, the diamagnetic clamp was commly made of carbon steel and the tailor-made calmp in the experiment was made of non-magnetic stainless steel.…”

“…Cold-rolled state 2024 aluminum alloy in the pulse magnetic field assisted tension [22][23][24], and the magnetic field accelerated the free radical pair transition from the singlet to triplet state between the dislocation and the obstacle. This reduced the bond energy between the dislocation and the obstacle, improved the dislocation mobility, and increased the dislocation density and refined grains.…”
