“…We have previously observed a similar rotation of basal poles in TD direction in the study of the texture of magnesium alloy with zinc, zirconium, and rare earth metals (REM) [9]. This was to the influence of additives of REMs to the magnesium alloy, which promote activation of nonbasal deformation mechanisms, particularly of prismatic and pyramidal slip of dislocations [9].…”

“…Effect of low-cycle alternating bending (AB) on crystallographic texture, microstructure and anisotropic properties of hexagonal magnesium alloys with aluminum and zinc (AZ31), zinc, zirconium and rare earth metals (ZE10), and titanium has been previously studied [4][5][6][7][8][9]. However, data on complex studies of the effects of the AB on the texture, structure, and anisotropy of elastic properties of magnesium alloys with lithium are absent.…”

The effect of low-cycle alternating bending at room temperature on the crystallographic texture, metallographic structure, and elastic properties of sheets of MgLi5 (mass) magnesium alloy after warm cross-rolling has been studied. Texture of alloy is differed from the texture of pure magnesium. The initial texture of alloy is characterized by a wide scatter of basal poles in the transverse direction. In the process of alternating bending, the changes in the initial texture and structure (which is represented by equiaxed grains containing twins) lead to regular changes in the anisotropy of elastic properties.

“…This helps to reduce residual stresses and favors the creation of a flat sheet [5]. Earlier it was shown that as a result of alternating bending, the original texture and, as a consequence, the physical and mechanical characteristics of the sheet are changed [6] that should be taken into account in the manufacture of products.…”

“…The alternating bending render most significant impact on the structural parameters and mechanical properties, which are sensitive to small deformations during tensile tests. These are texture, yield stress and twins [6,7]. The texture in [6,7] was represented using inverse pole figures (IPF) of the direction (ND) to the rolling plane (IPF ND).…”

The ZE10 magnesium alloy with the rare-earth metal additives, which contribute to a better forming of the alloy, was used as studied material. The ZE10 magnesium alloy with the rare-earth metal additives, which contribute to a better forming of the alloy, was used as studied material. Sheet material is usually straightened on roller levelers to relieve residual stresses and improve flatness. The metal is subjected to alternating deformation by bending when straightening. The changes in the structure, crystallographic texture and, as a result, physical and mechanical properties occur in the metal are often not taken into account in the future. The elastic modulus is an important parameter, for example, in the production of products using bending. In this work, the elastic modulus of sheets of magnesium alloy ZE10 was estimated in three main directions. A starting sheet was obtained by extruding an ingot, then rolling in the longitudinal direction and then rolling with a change in direction by 90° after each pass in combination with heating to 350°C. The original sheets were subsequently subjected to alternate folding. Evaluations were made of the elastic modulus of the original sheet, as well as the sheets after 0.5, 1.0, 3.0 and 5.0 alternating bending cycles. To estimate the elastic modulus, we used the Kearns texture parameters , which we calculated from the inverse pole figures, as well as the elastic constants of the single crystal of the ZE10 alloy found by us. The maximum deviation of the calculated and experimental values of the elastic modulus did not exceed 5.2%. Strong correlations and quadratic regression equations have been established between the values of the elastic modulus, mechanical characteristics (tensile strength, yield stress, elongation), on the one hand, and the above-mentioned parameters of the Kerns texture, on the other hand. The approximation reliability coefficients are 0.76 - 0.99.
