ИССЛЕДОВАНИЕ ИСКАЖЕНИЙ КРИСТАЛЛИЧЕСКОЙ РЕШЁТКИ В ТВЁРДОМ РАСТВОРЕ АЛЮМИНИЕВОГО СПЛАВА Д16 (АА2024) ПОСЛЕ ОТЖИГА И СТАРЕНИЯ

Annealing, quenching, natural and artificial aging at 100 200°С during 15 30 minutes of Al-Cu-Mg alloy D16 (AA2024) are provided. Chemical composition solid solution is found using scanning electron microscopy micro-X-ray-spectral analysis. Based on results chemical analysis the calculation average interatomic distance changing in found, which shows value crystal lattice distortion. Also distortion residual stresses studied X-ray It was annealed state lead to similar content alloying elements solution, mass percentage Cu 15…16 times Mg 4…5 higher than should be equilibrium accordance with diagram. Exposition for temperature does not significant difference level calculated measured. High stress quenched after short exposition before allows receiving high strength, but may give less exfoliation corrosion resistance water-salt environment.
