摘要：

The present study investigates the fatigue behaviour and impact strength of friction stir-welded (FSWed) carbon steel (AISI 1018) joints in comparison with the base metal (BM). The fatigue behaviour was tested using compact tension (CT) specimen of BM and FSWed joints under the constant amplitude load at different values of stress ratio (R) having a frequency of 10 Hz. A 20% increase in fatigue life along with a lower fatigue crack propagation rate was observed for FSWed specimens when compared to BM. The impact strength of BM and FSWed specimens was measured using the Charpy test. A higher value of impact strength was observed in FSWed specimens in comparison to BM. Additionally, regression analysis was carried out to model impact energy in terms of input parameters. Microstructural examination of a fractured surface of the FSWed specimen revealed the ductile fracture. A higher microhardness value was also observed in FSWed specimens when compared to BM.
