Özet

In this study, metallurgical properties of AISI 1040 steel and high-chromium white cast iron joined using friction welding process was investigated experimentally. Scanning electron microscopy, optical microscopy, energy-dispersive spectrometry, electron backscattered diffraction, X-ray diffraction and elemental mapping analysis were used to analyze the microstructures of the weld interfaces. The joint strength was evaluated with tensile testing and microhardness, and the fracture behavior was examined by SEM. HCrWCI and AISI 1040 steel were successfully welded using the FW. Increasing rotational speed was an effective parameter on the joint quality. The diffusion of Cr, C, Mn, Mo, Si and Ni elements occurred more in high-speed joints. The increase in plastic deformation caused the formation of fine grains and increased strength.
