Abstract
It was shown by X-ray diffraction that the aluminum crystal structure is distorted under conditions of nonequilibrium laser heating, which appears in lowering the lattice symmetry. A method for describing the observed distortions, based on the transition to a new unit cell, was proposed. It was shown that the distorted aluminum crystal structure can be described using the transition from the face-centered cubic cell to the monoclinic body-centered cell. The parameters of the aluminum unit cell after laser irradiation were determined as a = 0.2870 nm, b = 0.2860 nm, c = 0.4060 nm, and β = 90.013° (for the axes of the monoclinic body-centered lattice).
