“…In recent years, much attention has been drawn to the investigation of the inhomogeneity of the microstructure of aluminum alloy thick plate [14][15][16][17][18]. It is known that the inhomogeneity of the microstructure of aluminum alloy thick plate along the thickness direction is related to the forming technology.…”

“…Zhao et al [14] found that the inhomogeneous distribution of precipitates was caused by the nonuniform deformation and cooling rates. Yin et al [15] studied the quench sensitivity of Al-Cu-Mg alloy thick plates, and their experimental results exhibited a dramatic decrease in the quench cooling rate from the surface to the center of the plate, and the inhomogeneous quenching caused the difference in the microstructure. Zhou et al [16] observed that the increase in the average pass reduction ratio (APRR) during hot rolling was beneficial to the formation of weaker shear texture, and it improved the uniformity of the mechanical properties of aluminum alloy thick plate.…”

2519A aluminum alloy thick plate is a promising structural material in the field of military industries, owing to its low density, high tensile strength and excellent ballistic performance. However, the nonuniformly distributed microstructure along the thickness direction of this alloy leads to delamination cracks, which restrict its further application in light armor fields. In order to understand the mechanism of delamination cracking along the thickness direction, the effect of the microstructure on the mechanical properties of 2519A aluminum alloy in the thickness direction was investigated. The results show that the elongation and critical stress intensity factor values (ΔKcr) of the alloy in the thickness direction are 45.8% and 44.1% lower than the values in the rolling direction, respectively. The low mechanical properties of the alloy may be due to the short distance between the second phase, the weak binding force of grain boundaries and the disharmonious deformation caused by the inhomogeneous distribution of the microstructure. This study provides a basis for improving the mechanical properties and delamination cracking of the alloy along the thickness direction.

“…This is even more doubtful if the DSC peaks are used for the determination of activation energies for the precipitation of specific phases, such as in many works, (e.g. [7][8][9][10][11][12][13][14][15]), for instance, by applying evaluation methods like the Kissinger method [16].…”

In situ high-energy X-ray diffraction of precipitation and dissolution reactions during heating of Al alloys

et al. 2021

During heating of Al alloys, typically a sequence of precipitation and dissolution reactions occurs and the single (partly opposing) reactions superimpose. Differential scanning calorimetry (DSC) is one common technique to analyse the kinetic development of precipitation and dissolution in Al alloys, but the superposition of the exothermic precipitation and endothermic dissolution reactions complicates the DSC signal interpretation, as DSC measures the sum of any heat effect. Synchrotron high-energy X-ray diffraction (HEXRD) allows the kinetic development of phase transformations to be obtained and can support the separation of superimposed DSC signals. HEXRD results from this work offer a new approach to separate part of the superimposed reactions and their kinetic development for the equilibrium phases β-Mg2Si in EN AW-6082 and η-Mg(Zn,Cu,Al)2 in EN AW-7150. Comparing DSC and HEXRD results confirms serious overlap issues. Common DSC evaluation methods alone, using zero crossing between endothermic and exothermic heat flow or peak positions can be misleading regarding individual reaction start and finish temperatures as well as regarding reaction intensities, which can be unambiguously determined by in situ HEXRD.
