The microstructure of the joint has been analyzed with the use of a light electron microscope and compared with the results of microhardness analysis. Fatigue properties were established in low-cycle fatigue tests with constant true strain amplitude equal to ε = 0.25%. The obtained amplitudes of stress and plastic strain have been presented in this paper. The fatigue fracture in the tested sample was analyzed with the use of a scanning electron microscope.
