Abstract

Abstract AISI 430 and HARDOX 450 grades were combined using tungsten inert gas double-sided welding process. Microstructural changes were evaluated with scanning electron microscope, energy dispersive spectrometry, electron back scatter diffraction, elemental mapping, X-ray diffraction analysis. Mechanical diffenrences of welded alloys were determined by tensile, notch impact and microhardness tests. Failure surfaces of tensile samples were examined by SEM. The maximum tensile strength was 513.59 MPa and the impact energy was 77 J at welding speed of 0.01 m min−1 at current of 475 A. The lowest hardness was determined in HAZ due to excessive grain size. Failure exhibited brittle fracture and cleavage planes.
