Abstract
etallographic studies of deposited metal of dispersion-hardening steel of Fe-C-Ni-Cr-Si-Al-Cu system have been conducted. It is shown that secondary hardening of deposited metal proceeds in two stages, depending on tempering duration. In the first stage it proceeds through residual austenite decomposition and martensite formation. In the second stage with longer duration of tempering, martensite decomposes with formation of new phases, namely high-alloyed ferrite and dispersed inclusions with a higher content of silicon and nickel.
Keywords: arc surfacing, surfacing materials, selfshielded flux-cored wires, dispersion hardening, structure
