Resumen

In this study, the Charpy V-notch (CVN) values were investigated in all directions [longitudinal-transverse (L-T), T-L, short-transverse (S-T), T-S, L-S, S-L, and at 45°] with respect to the rolling direction (RD) of American Petroleum Institute (API) 5L X52 steel welded by electric resistance welding (ERW). In addition, the microstructures and fracture surfaces were examined by scanning electron microscopy (SEM). The Charpy specimens were machined according to ASTM E23 and tested at room temperature. The experimental results showed that the CVN values depended on the direction of the RD. Additionally, a fracture surface analysis performed with SEM showed fibrous fracture, dimples, and secondary cracks. Microstructures of ferrite and perlite were obtained, which are typical of X52 steel. Graphical abstract: [Figure not available: see fulltext.].
