Abstract
In this study, HARDOX 450 and AISI 430 grades are combined using double-sided tungsten inert gas (TIG) welding process. Microstructural properties of weld zone were evaluated with optical microscope (OM), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), electron back scatter diffraction (EBSD), elemental mapping analysis. After tensile testing, fracture surface morphology was evaluated using SEM. The width and depth of the weld seam increased with the increase in current. Carbon and chrome diffusion gradients were formed on the HARDOX 450 steel side by FSS in welded joints. The crystallographic plane was dominated by blue and, concentrated in the direction of {101}, {001}, {111}.
