| مستخلص: |
Al-Li-based alloy of a third-generation containing 3.71% Cu, 0.91% Li, 0.31% Mg, 0.15% Zr, and 0.05% Fe was prepared by twin-roll and mold casting. Thin specimens were in-situ annealed in TEM up to 450 °C, and the transformation of boundary eutectic particles was monitored. The combination of TEM images with signals from several detectors, including conventional STEM and SEM detectors and ACOM-TEM system, provided complex information about the decomposition of primary phase particles and their transformation into new ones. Dissolution of complex Al-Cu-Li primary particles occurs above 400°C, and it is accompanied by a formation of Al-Cu-Li and Al-Cu phases. [ABSTRACT FROM AUTHOR] |
