Аннотация
Plates from alloy AA7020 (Al – Zn – Mg) with a thickness of 4.5 mm are studied after T6 heat treatment and friction stir welding. Tensile and bending tests are performed. The hardness of the welds is measured in transverse direction. The microstructure over cross section of a weld is studied by the methods of light and transmission electron microscopy. The weldability of alloy AA7020 by friction stir welding is shown to be high.
