Abstract

In this study, effect of rotational speed on the characteristic microstructure and mechanic properties of the AISI 1030/AISI 420 stainless steel couple welded by friction welding method was experimentally investigated. The weld joints were produced with 1400, 1500, 1600 rpm rotational speed, under 40 MPa process friction pressure and 60 MPa forging pressure for a friction time of 4 s and a forging time of 6 s. After friction welding, the bonding interface microstructures of the samples were examined by scanning electron microscopy (SEM), optical microscopy (OM), energy dispersive spectrometry (EDS) and X-Ray diffraction (XRD) analysis. Furthermore, microhardness and tensile tests were applied to determine the mechanical behavior of weld joints. In addition, fracture types of the tensile test samples were determined from the fractographic examinations by using SEM and EDS. The result of the applied tests and observations pointed out that the mechanical properties and the microstructure changed depending on the increased rotational speed.
