Comparative analysis of the structure and phase composition of plates from aluminum alloy 7050 in state T7451 is performed by the methods of light and electron microscopy. Factors influencing the fatigue endurance are determined. Data on changes in the microstructure of specimens of alloy 7050 in long-term holds at 121 and 163 °C are obtained right on the object stage of the microscope.
