Popis: The structure, mechanical properties and deformation behavior of welded joints of 17Mn1Si pipe steel modified by means of surface ultrasonic impact straining and combined pulsed mechanical-electrophysical treatments have been studied. Welded steel plates of 10 mm thickness were used for specimens’ preparation. In doing so, their gauge length comprised of the heat affected zone and directly the weld region. It is shown that the proposed treatment techniques provide hardening of the surface layer, as well as increase in tensile strength. The revealed differences in the structure modification and deformation behavior of the specimens subjected to different treatment methods are illustrated and discussed.
