Resumo
The structure of the contact lines and of the thermomechanically affected zone of welded joints of medium-carbon steels obtained by rotary friction welding have been studied using metallography and scanning electron microscopy supplemented with X-ray electron microprobe analysis. The results of the microhardness distribution over the cross section of the welded joint are presented. The phase transformations realized at each stage of the technological process of welding in the regions subjected to the thermodeformation influence have been analyzed. The results of the uniaxial tensile and impact bending tests supplemented by the fractography of the fracture surface are presented.
